AN NISAA' — Ayat 22

وَلاَ تَنكِحُواْ مَا نَكَحَ آبَاؤُكُم مِّنَ النِّسَاء إِلاَّ مَا قَدْ سَلَفَ إِنَّهُ كَانَ فَاحِشَةً وَمَقْتًا وَسَاء سَبِيلاً

And do not marry those [women] whom your fathers married, except what has already occurred. Indeed, it was an immorality and hateful [to Allah ] and was evil as a way.
