'Aisha was actually somewhat a lucky girl that she was handed over to Muhammad at the age of 9 years.

While the actual Islamic Ruling is:

  •  Even a breastfed small baby girl can be married, and husband can undress her, and take every kind of sexual pleasures with her naked body (like kissing her naked body and rubbing his penis in her thighs to ejaculate. 
  • And if the Husband thinks she is strong enough at the age of 5 years to bear the pain, then he can also penetrate in her vagina. And if the husband makes a mistake and harms the minor girl by penetrating in her vagina, still he has committed no sin or crime.
The largest Islamic website islamweb.net gave this fatwa(link):
الاستمتاع بالزوجة الصغيرة.. رؤية شرعية ۔۔۔
Taking sexual pleasure from minor girl according to Sharia. 
فإنه لا حرجَ في تقبيلِ الزوجة الصغيرة بشهوة والمفاخذة ونحوَ ذلك ولو كانت لا تطيقُ الجماع وقد بيَّنَ العلماء أن الأصلَ جوازُ استمتاع الرجل بزوجته كيف شاء إذا لم يكن ضرر وذكروا في ذلك استمناءَه بيدها ومداعبَتها وتقبيلَها وغير ذلك
There is no problem to kiss the minor girl wife with intention of sexual pleasure and to do "مفاخذہ" which is to rub the penis between her thighs in order to ejaculate the sperms, or to do any other similar act. All these acts of sexual pleasure are permitted, even if she does not possess the power for penetration. According to Ulama, a husband is free to enjoy her in every way till the time no harm is done to her. So, the minor girl could masturbate him, foreplay could be done with her, she could be kissed and similar other things.
Then this same website cites tens of Fatawa from Salaf Ulama about this (link)
And another one of the largest Website of Muslims is Islamonline.net, which says the similar thing (link):
فإنه لا ضررَ في الإنزالِ بين فخذي الصغيرة التي لا تطيقُ الجماع وتتضررُ به إذا كان ذلك الإنزالُ بدونِ إيلاج، وقد بَيَّنَ العلماءُ أن الأصلَ هو جوازُ استمتاعِ الرجلِ بزوجتِه كيف شاء إذا لم يكن ضرر
There is no problem if husband rubs his penis between the thighs of minor girl in order to ejaculate the sperm, even the minor girl does not possess the ability for penetration... According to the Islamic Scholars husband is allowed to enjoy the minor wife in every possible way till the time she is not harmed.

 
At some point, we have to leave the 1400 years old rules and Sharia. There is no other way out. For example, the Quran says that even a minor girl (under age of 9) could be married and penetrated.
(Quran 65:4) And if you are in doubt about those of your women who have despaired of menstruation, (you should know that) their waiting period is three months, and the same applies to those (minor girls) who have not menstruated as yet.
Modoudi's Tafseer of verse 65:4 (link):
They may not have menstruated as yet either because of young age, or delayed menstrual discharge as it happens in the case of some women, the waiting-period of such a woman is the same as of the woman, who has stopped menstruation, that is three months from the time divorce was pronounced.
Here, one should bear in mind the fact that according to the explanations given in the Qur'an the question of the waiting period arises in respect of the women with whom marriage may have been consummated, for there is no waiting-period in case divorce is pronounced before the consummation of marriage. (Al-Ahzab: 49). Therefore, making mention of the waiting-period for the girls who have not yet menstruated, clearly proves that it is not only permissible to give away the girl in marriage at this age but it is also permssible for the husband to consummate marriage with her. Now, obviously no Muslim has the right to forbid a thing which the Qur'an has held as permissible.
And the largest Muslim Fatwa website Islam Questions Answers says there is a Consensus (i.e. Ijma) upon it among all the Salaf (i.e. early) generations of Muslims:
https://islamqa.info/en/12708
Marriage to a young girl before she reaches puberty is permissible according to sharee’ah, and it was narrated that there was scholarly consensus on this point (i.e. All jurists along with 4 Imams agree upon it) ... The scholars are (also) unanimously agreed (Ijma) that a father may marry off his young (minor) daughter without consulting her.
At another place, this same Saudi Mufti writes:
https://islamqa.info/en/27305
If she has not reached the age of puberty, then her father has the sole right to arrange her marriage and does not have to ask her permission
Ibn Qudaamah (may Allaah have mercy on him) said: With regard to a virgin who is still a minor, there is no difference of opinion concerning her (i.e., that her father may marry her off even if she objects). Ibn al-Mundhir said: Every scholar from whom we learned was agreed that it is permissible for a man to marry off his virgin daughter who is still a minor, if he marries her to someone who is compatible, and it is permissible for him to marry her off even if she objects and refuses.” Al-Mughni, 9/398
Here is a fatwa from a Hanafi Deoband Mufti (link):
Question:
Is it allowed to penetrate into a wife who is still a minor-girl? ....
Answer:
....Yes, it is allowed to penetrate into a wife who is still a minor-girl, nevertheless guardians of the minor girl should keep it in mind and marry her by keeping this issue in their minds ... 
Fatawa Alamgiri (Authentic Book of Hanafi Fiqh) (link):
Translation:
And the correct view is this that it is allowed to penetrate too in the vagina of that minor girl, who is strong enough and her vagina and anus does not become one due to penetration ... and if a (non-adult) boy of age 10 penetrates in the vagina of a woman, then there is no bathing for the boy, while woman has to take a bath ... and if an adult man penetrates into a non-adult girl, then adult man has to take the bath, but bath is not obligatory upon the non-adult girl.

Imam Bukhari on Nikah with minor child girl:

Imam Bukhari gave the following heading to the chapter about marriage of Aisha:
Sahih Bukhari, Book of Marriage (link):
باب إِنْكَاحِ الرَّجُلِ وَلَدَهُ الصِّغَارَ
A man can give his minor daughter in marriage 
لِقَوْلِهِ تَعَالَى: {وَاللاَّئِي لَمْ يَحِضْنَ} فَجَعَلَ عِدَّتَهَا ثَلاَثَةَ أَشْهُرٍ قَبْلَ الْبُلُوغِ.
Allah said (in Quran 65:4): ... and for those minor girls who didn't start mensturating. This means their waiting period is 3 months
عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم تَزَوَّجَهَا وَهْىَ بِنْتُ سِتِّ سِنِينَ، وَأُدْخِلَتْ عَلَيْهِ وَهْىَ بِنْتُ تِسْعٍ، وَمَكَثَتْ عِنْدَهُ تِسْعًا‏.‏
Narrated `Aisha:
that the Prophet (ﷺ) married her when she was six years old and he consummated his marriage when she was nine years old, and then she remained with him for nine years (i.e., till his death).
Imam Ibn Hajar al-Asqallani writes in his commentary of Sahih Bukhari (link):
" يجوز تزويج الصغيرة بالكبير إجماعا ولو كانت في المهد"
It is unanimous (Ijma) that an adult man can marry any minor girl, even if she is so small that she is in a cradle. 

Verse 4:3 also proves marriage with small girls

If a minor orphan girl is in guardianship of any man, then he could marry her even without her consent.
(Quran 4:3) And if you fear that you shall not be able to deal justly with the orphan girls, then marry (other) women of your choice ...
Sahih Bukhari, Book of Nikah (link): 
Narrated Aisha":
(regarding) the Verse: 'And if you fear that you shall not be able to deal justly with the orphans...' (4.3) It is about the orphan girl who is in the custody of a man (due to her minor age) who is her guardian, and he intends to marry her because of her wealth, but he treats her badly and does not manage her property fairly and honestly. Such a man should marry women of his liking other than her.

Due to penetration in minor girls, their vagina and anus could become one & the husband will decide when to penetrate in her vagina

There is risk of permanent damage to the minor girl that due to penetration, her vagina and anus could become one.
Shia Imam Khomeini wrote.

مسألة 12 : لا يجوز وطء الزوجة قبل إكمال تسع سنين ، دواما كان النكاح أو منقطعا ، و أما سائر الاستمتاعات كاللمس بشهوة و الضم و التفخيذ فلا بأس بها حتى فى الرضيعة ولو وطئها قبل التسع ولم يفضها لم يترتّب عليه شي‏ء غير الإثم على الأقوى، وإن أفضاها - بأن جعل مسلكي البول والحيض واحدا أو مسلكي الحيض والغائط واحدا - حرم عليه وطؤها أبدا، لكن على الأحوط في الصورة الثانية. وعلى أيّ حال لم تخرج عن زوجيّته على الأقوى، فيجري عليها أحكامها من التوارث وحرمة الخامسة وحرمة اُختها معها وغيرها
Tahreer al-Waseelah, volume 2, page 343
Issue #12: It is not permissible to have sexual intercourse (with one’s wife) before she reaches 9 years in age, be it in Nikaah (permanent marriage) or Mut’a (temporary marriage). As for all other pleasures such as lustful touch, embracing, and thighing, there is no problem in it, even if she is a suckling baby. A man having intercourse with a girl younger than nine years of age has not committed a crime, but only an infraction, if the girl is not permanently damaged by vagina and anus becoming one. If the girl, however, is permanently damaged, the man must provide for her all her life. But this girl will not count as one of the man's four permanent wives. He also is not permitted to marry the girl's sister.
Sunnis also know about this danger. Thus, we read in Fatawa Alamgiri (Authentic Book of Hanafi Fiqh) (link):
And the correct view is this that it is allowed to penetrate too in the vagina of that minor girl, who is strong enough and her vagina and anus does not become one due to penetration ...
The question is, who will decide if she is strong enough that her vagina and anus will not become one due to penetration? 
And the answer is, it is the husband who has to decide it. 
But a husband is neither a doctor, nor he can understand this issue as a man. Actually, even a team of expert doctors cannot judge if a 5 or 6 years old girl has become ready for penetration or not. Neither husband nor doctors nor parents are able to judge it.
Moreover, you leave a minor girl alone at the mercy of the husband. And then you allow that he undress her and start playing with her naked body. Do you think that he can still make a sensible decision in such a state of mind, and he will not penetrate in her vagina out of lust? 
 

Buying minor slave girl for sexual pleasure

If minor girl is not available for Nikah, then still a path is open for Muslim man to buy a minor slave girl, and the take sexual pleasure from her.

Imam Abdullah Ibn Abi Zayd (who is also known as younger Imam Malik), writes in his Fiqh book (link):

واستبراء الامة في انتقال الملك حيضة انتقل الملك ببيع أو هبة أو سبي أو غير ذلك. ومن هي في حيازته قدحاضت عنده ثم إنه اشتراها فلا استبراء عليها إن لم تكن تخرج. واستبراء الصغيرة في البيع إن كانت توطأ ثلاثة أشهر
Translation:
The istibrā' (waiting) period for a slave concubine who changes ownership is one menstruation. Ownership may change by selling, giving away, capture, or any other way. If the slave is a minor girl and she starts menstruating after being taken in possession by her new owner, then she does not have to go through a period of istibrā' (i.e. waiting period). But if the previous owner had already did sex with her, then there is a waiting period of 3 months for her before new owner can have sex with her. 

And Imam Ibn Qayyam al-Jawziyya recorded (link): 

وفي الفصول روى عن أحمد في رجل خاف ان تنشق مثانته من الشبق أو تنشق انثياه لحبس الماء في زمن رمضان يستخرج الماء ولم يذكر بأي شيء يستخرجه قال وعندي أنه يستخرجه بما لا يفسد صوم غيره كاستمنائه بيده أو ببدن زوجته أو أمته غير الصائمة فإن كان له أمه طفلة أو صغيرة استمنى بيدها
It is narrated from Imam Ahmad bin Hanbal that one person came to him who feared of ejaculating the sperms during fasting. Imam Ahmad told him:"You could ejaculate in a way which does not break your fast. He could masturbate with his hands, or let his wife to masturbate him, or a slave woman who could do it, even if that slave girl is a minor, still she could masturbate him with her hands.

Naked minor slave girl serving his Muslim Owner in year 1910 before Islamic Slavery was abolished

 

It was a regular practice of Muhammad's Companions to rape prepubescent slave-girls

Ali raped a slave-girl on the same night when she was made captive after the war.

Musnad Ahmad, Hadith 22967:

Narrated Buraydah: 
I hated Ali as I had never hated anyone. ... The Prophet sent to us Ali, and among the female captives was a slave girl who was the finest of the female captives, and he apportioned the Khums (one-fifth of war booty given to the Prophet and his family). Ali divided the shares, and his head was dripping (after taking a ritual bath following sexual intercourse with the slave-girl). We said: "O Abu al-Hasan (i.e. Ali), what is this?!" Ali replied: "Did you not see the slave-girl who was among the female captives? I divided the shares and apportioned Khumus. Then she became part of the Khumus. Then she became part of the household of the Prophet, and then she became part of the house of Ali, and (thus) I had sexual intercourse with her." ...
Grading: Classed Sahih by al-Arna'ut

Istibra is a period of sexual abstinence required till the first period of captive girl is over. This is to ensure no confusion on paternity. Since Ali raped that captive girl the same night without any Istibra, thus some people criticized this action of Ali.

Ibn Hajar al-Asqallani answered this criticism, and wrote:

وقد استشكل وقوع على على الجارية بغير استبراء وكذلك قسمته لنفسه فأما الأول فمحمول على أنها كانت بكرا غير بالغ ورأى أن مثلها لا يستبرأ كما صار إليه غيره من الصحابة
"It was problematic that Ali Had sexual intercourse with the slave-girl without observing Istibra, and also that he apportioned a share for himself.
As for the first issue, it is understood that she was a virgin and not pubescent. He recognized that someone like her need not observe Istibra, and it is in accordance with the practice of other Companions."
Ibn Hajar, Fath al-Bari 8/67.

Please imagine the trauma of those small girls. Their fathers and brothers were killed the same day by Muslims, and then they were driven out of their houses and looted by Muslims, and then they were even separated from their mothers the same night, and then an ugly Jihadis started raping those small girls.

Muhammad didn't even grant the poor small girls the period of one month to come out of the shock of killing of their fathers and brothers (like the Jews/Christians did), before raping them. 

If any God really exists, then can He ever bring such a shame to humanity?

Unfortunately, Muslims have lost all their Humanity, and all their Shame due to the religious brainwashing. They still come out and start defending Muhammad against this ugliest crime which he committed against humanity. 

This was the practice of Companions and all Muslims of the last 1400 years, till the secular non-religious West saved humanity against these evil religious practices of slavery and raping.

8-Year-Old Yemeni Child Dies at Hands Of 40-Year-Old Husband on Wedding Night

An eight-year-old child bride died in Yemen on her wedding night after suffering internal injuries due to sexual trauma. Human rights organizations are calling for the arrest of her huchild marriages in mioddle eastsband, who was five times her age.
Al Nahar, Lebanon, reported that the death occurred in the tribal area of Hardh in northwestern Yemen, which borders Saudi Arabia. This brings even more attention to the already existing issue of forced child marriages in the Middle East.
"According to the United Nations Population Fund (UNFPA), between 2011 and 2020, more than 140 million girls will become child brides. Furthermore, of the 140 million girls who will marry before the age of 18, 50 million will be under the age of 15."
It is reported that over a quarter of Yemen's young girls are married before the age of 15Not only do they lose access to health and education, these child brides are commonly subjected to physical, emotional and sexual violence in their forced marriages.
