22وَلا تَنكِحوا ما نَكَحَ آباؤُكُم مِنَ النِّساءِ إِلّا ما قَد سَلَفَ ۚ إِنَّهُ كانَ فاحِشَةً وَمَقتًا وَساءَ سَبيلًا(Irfan-ul-Quran)And do not marry women whom your fathers and forefathers married. But that which has passed (before this command is forgiven). It is indeed highly indecent, infuriating and an evil custom.
