According to a top medical journal, minor marriage and childbirth is very safe throughout the world, far safer than marriage and childbirth after age 29. Existing data indicates that marriage and childbirth at early ages (e.g., 15-19) is extremely safe. The data suggest that if we want to name and shame cultures for endangering women, we should stigmatize those (liberal) cultures which encourage marriage and childbirth after ages 20-25 - as danger to women rapidly increases after this age. 

Danial: 15 to 20 years old MINOR girls

Answer: It is not about being a "minor", but about the "age of consent"

Dear People, 

Please understand that the religion of Islam works as a cult, where its followers are very easily manipulated and deceived by Islamic preachers like Daniel. 

Daniel is very clearly deceiving them by calling 15 to 20 years old girls "minors" in this matter. 

The term of "minor" in the world is used for LEGAL issues (like drinking, driving licence, crimes etc.). And it is 18 years. 

Nevertheless, the issue is about the "marriage", and it is not about being a minor, but it is about the "age of consent".

And this "age of consent" in Europe and almost all over the world is 16 years (link).

Unfortunately, his Muslim followers are not in a position to figure out this deception, while religion makes people often blind. This is the main reason why religions are so successful in brainwashing their followers.

Islam allows men to marry minor girls, and penetration in their vaginas starts at the age of 8 or 9 years or even earlier if they think that the prepubescent girl is strong enough to bear the pain of penetration. Nevertheless, men (neither the father of the girl nor the husband nor any medical doctor) are in a position to find out if an 8 or 9 or 10  years old girl is ready for penetration. This results often in the painful suffering of Viginal Fistula among girls (link). 

A vaginal fistula is an abnormal opening between the vagina and other nearby organs in the pelvis, including the bladder or rectum. A fistula can cause many complications, such as urinary and fecal leakage, abnormal vaginal discharge, tissue damage, kidney infections and other irritative type symptoms.

In his promotion of minor marriage, Daniel promotes impregnating 9 or 10 year olds to "extend the fertility window", through the practice of marriage to an old man marrying, or having sex with 9 years old prepubescent girls. He calls it to be a tradition (Reference: Youtube Video of Daniel Haqiqatjou)

Therefore, if Daniel really wants to defend the Sharia Ruling of having sex with minor girls, then he should bring a scientific study which deals with girls from 9 years and onwards. 

Secondly, this study of 15 to 19 years old girls (which Daniel mentioned) is also not showing accurate results. We know that in almost all countries of the world, marriage is legal only after 18 years. Thus, most of the girls in this group of 15-19 years are actually getting married at the age of 18 or 19 years, while some of them may be between 16 to 17 years too, but there are only a few who marry at the age of 15 and get babies.

Childbirth is still dangerous at the age of 15 years, as it becomes clear from other studies. For example, look at the following study: 

https://obgyn.onlinelibrary.wiley.com/doi/full/10.1111/j.1600-0412.2012.01467.x 

". ......girls aged 15 or under had an odds ratio for maternal death four times higher than women aged 20–24. "

Regarding the Vaginal Fistula, please read this study:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3877393/

"In sub-Saharan Africa and South Asia, obstetric fistula is very common, as access to and use of emergency obstetric care is limited ...... Several factors have been linked to the high occurrence of obstetric fistula in sub-Saharan Africa, including the preponderance of early marriage and teenage pregnancy, which in turn mean that the girls do not have pelvises which have sufficiently developed to allow reproduction [10]. This is further compounded by the poor nutritional status of most of the girls who live in these highly deprived settings [11,12]."

Aid workers confirm death and fistulas are the problems:

"The greatest danger, however, is to the pelvic floor. Girls may start ovulating and menstruating as early as age 9, though the average is around 12 to 13. ........ Just because a girl can get pregnant, though, doesn't mean she can safely deliver a baby. The pelvis does not fully widen until the late teens, meaning that young girls may not be able to push the baby through the birth canal. The results are horrific, said Wall and Thomas, who have both worked in Africa treating women in the aftermath of such labors. Girls may labor for days; many die. Their babies often don't survive labor either.

Moreover, the high mortality rate among children from teen mothers is not the only problem, but they suffer from other horrific health problems too, the whole of their lives.

Is all this Data Islamophobic?

PS:

Women in the Western world don't hesitate to get children after the age of 29, while medical facilities have made childbirth safer even after 29 years. It is reflected in the chart itself, that Daniel presented. The link to the direct scientific study is here
