(Respect for the Father)
Do not marry the women who were previously married to your fathers – existing marriages are exempted and shall not be broken – for it is a gross offense, and an abominable act.
وَلا تَنكِحوا ما نَكَحَ ءاباؤُكُم مِنَ النِّساءِ إِلّا ما قَد سَلَفَ إِنَّهُ كانَ فٰحِشَةً وَمَقتًا وَساءَ سَبيلًا
wa laa tankihoo maa nakaha aabaaa’ukum minan nisaaa’i illaa maa qad salaf; innahoo kaana faahishatanw wa maqtanw wa saaa’a sabeelaa
