differences. These differences indicated that they were subject to on the laws that regulated other beings in terms of reproduction.
....Since Hazrat Adam and Hazrat Eve were prone to a carnal power called lust, they were not an exception to the reproductive system in nature. They were married by the consent of Allah Almighty, and then Hazrat Eve became pregnant for the sake of Allah Almighty.
....It has been narrated that Hazrat Eve gave birth 20 times. The final child was a single child, Seth. The result of all earlier pregnancies was fraternal twins, one boy and one girl.
....What are fraternal twins?
....Fraternal (dizygotic) twins occur when the mother releases two eggs and both become fertilized, resulting in twins; these can both be male or both female, sometimes they can be of different genders. Such twins have some differences from identical twins. Just as they can be of different sexes, their characters can be very different and they do not have to resemble one another.

....THE MARRIAGE OF HAZRAT ADAM'S CHILDREN
....Ten suhuf (small booklets) were revealed to Hazrat Adam, the first human being and prophet, and he was obliged to obey the divine commandments found in these pages. These commandments forbid the twins to marry one another. Other sibling marriages were permitted, as at this time there was no other option.
....Hazrat Adam began to marry his children to each other. It was time for Kabil and Habil (Cane and Able) to get married

....Kabil's twin sister was prettier than that of Habil. When Hazrat Adam said that Kabil was to marry the twin sister of Habil and that Habil should marry the twin Kabil, Kabil objected, and said that he would marry his own twin as she was more beautiful.
....Yet, there was a commandment forbidding such a marriage. Enraged, he killed his brother, Habil. This was the first murder on the Earth.
....As he had married off his children when they had reached an age to marry, Hazrat Adam then began to marry off his grandchildren who were mature.
....After descending from Paradise to the Earth, Hazrat Adam and Hazrat Eve lived for one thousand years. In those years, the number of their descendents reached 40,000.
