Dear Mr. ben Pesach,
last week I was invited by friends for a small party. There I talked with a guy about the bible and Islam.
He said to me that after Kain has killed Abel, he married a woman. This woman can only be his sister. So all his offspring is innbreed. I should read the quran, it is much better.
I answered him, that I know, that he has in Islam the same problem, because Mohammed mentioned in the quran the story of Adam and Eve too. Two humans were in the quran the first people, so in his logic he must say the same about the quran.
But I told him, that I do not know enough about this "inbreed" issue and I will ask somebody, who knows more about it.
What can I tell him?
Sincerly,
Ullrich
