Sahih Muslim 1442b:

(The Prophet said) I intended to prohibit cohabitation with the suckling women, but (then) I considered the Greeks and Persians, and saw that they suckle their children and this thing (cohabitation) does not do any harm to them (to the suckling women).

This hadith is solid evidence that there is no entity named Allah in the sky. Rather, Muhammad himself was creating the laws and later attributing them to divine revelation. For those who possess reason, this single hadith is enough to bring down the entire edifice of Islam.

If the people of Persia and Rome did not exist, there would be a prohibition in Islamic law against having sex with nursing women, and Muslims would be bringing lame excuses for this scientific error just as they try to justify the scientific error regarding the waiting period of a pregnant woman.

Sunan Abi Dawud 2158:

(The Prophet said): It is not lawful for a man who believes in Allah and the last day to water what another has sown with his water (meaning intercourse with women who are pregnant)

But science clearly proves that Muhammad was mistaken about pregnancy. Once a woman is pregnant by one man, no matter how much another man has intercourse with her, it does not affect the fetus and no DNA changes take place in it. These were the beliefs of the age of ignorance that Muhammad followed. Due to Muhammad's error regarding pregnancy, a woman is once again the one to suffer. During pregnancy, she cannot marry another man, fulfill her sexual desires, gain another man's love and support, and is forced to endure the painful journey of pregnancy alone.

If a man shows love and attention to a pregnant woman, making her happy and ultimately benefiting the fetus, what could be wrong with that?

Why would religion advocate for a pregnant woman to stay alone and suffer, ultimately causing harm to both her and the fetus?

Furthermore, look at this hadith where Muhammad initially denied any punishment in graves, but later copied it from a Jewish woman. 

Sahih Muslim, 584:

'A'isha reported: The Prophet (ﷺ) entered my house when a Jewess was with me, and she was saying, "Do you know that you would be put to trial in the grave?" The Messenger of Allah (ﷺ) trembled on hearing this and said, "It is the Jews ONLY who would be put to trial." 'A'isha said: We passed some nights, and then the Messenger of Allah (ﷺ) said, "Do you know that it has been revealed to me: 'You would be put to trial in the grave'?"

For those who think and understand, this event contains complete signs that they may recognize the truth.
