Surah An-Nisa, Verse 22

وَلَا تَنكِحُواْ مَا نَكَحَ ءَابَآؤُكُم مِّنَ ٱلنِّسَآءِ إِلَّا مَا قَدۡ سَلَفَۚ إِنَّهُۥ كَانَ فَٰحِشَةٗ وَمَقۡتٗا وَسَآءَ سَبِيلًا٢٢

walā tankiḥū mā nakaḥa ābāukum mina l-nisāi illā mā qad salafa innahu kāna fāḥishatan wamaqtan wasāa sabīlan

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