Q: I have been listening to the stories of the Prophets alaihimus salaam. I started with Aadam alaihis salaam and would just like to know after Aadam and Hawa alaihimas salaam had children how did the reproduction system start? The children were brothers and sisters so how did marriage etc work?
A: She would usually give birth to twins; one boy and one girl. The children of one pregnancy were allowed to get married to the children of another pregnancy. One was not allowed to marry a child of the same pregnancy. This was permissible for that era only.
