If Adam out of sheer anger had said to Eve "talaq, talaq, talaq", according to Islamic law, as given by Allah to Muhammed, Adam would have divorced Eve. Now if Adam and Eve resolve their differences amicably, Islam forbids them from coming together again until Eve is married to and divorced by another man. This means another man must first sleep with Eve for as long as he wants and then divorce her before she can return to her first marriage. Now my question to the Muslims is how will Eve sleep with another man when she is the mother of all? Won't this
stupid law result in incest if it were applied to Adam and Eve?

What happens when in the course of marrying another man she gets pregnant for that man? Will it be lawful to return to her first husband with the child of another man?

What is the relevance of this law? What is this law trying to achieve? If anything, it looks like the law seeks to promote immorality which is rife in Islam.
