incest

Respected scholars, as-salamu `alaykum. We all heard about the case of the incestuous relationship in Germany where a young man had an intimate relationship with his sister and they had four children and now they are going through legal channels to legalize their marriage. Now the question is this: We know that incest is forbidden in Islam, but what about the children who are born of such a relationship? Should they be ascribed to their father and mother who are siblings? And what is the role of the society towards such children in light of Islam? Jazakum Allahu khayran.

As-Salam `Alaykum, I have a question which is somehow strange. What does Islam say about the case of a brother marrying his sister unknowingly and there are children, who happen to be the product of this marriage?

As-salamu `alaykum. My name is faezah. I would like to know the Islamic point of view on incest. In Malaysia, incest is now rampant and the laws are not sufficient in curbing this heinous crime. Do you have any recommendation on how to curb this crime?
