“I came to the Messenger of Allah, and I was married to two sisters whom I had married during the Ignorance period. He said: 'When you go back, divorce one of them.' ”  

قَدِمْتُ عَلَى رَسُولِ اللَّهِ ﷺ وَعِنْدِي أُخْتَانِ تَزَوَّجْتُهُمَا فِي الْجَاهِلِيَّةِ فَقَالَ إِذَا رَجَعْتَ فَطَلِّقْ إِحْدَاهُمَا  

'I came to the Prophet and said: 'O Messenger of Allah! I have become Muslim and I am married to two sisters.' The Messenger of Allah said: 'Divorce whichever of them you want.' ”  

أَتَيْتُ النَّبِيَّ ﷺ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنِّي أَسْلَمْتُ وَتَحْتِي أُخْتَانِ قَالَ رَسُولُ اللَّهِ ﷺ لِي طَلِّقْ أَيَّتَهُمَا شِئْتَ
