Narrated by:Qais bin Harith said
It was narrated that Qais bin Harith said:“I became Muslim and I had eight wives. I went to the Prophet and told him about that. He said: 'Choose four of them.' ”
حَدَّثَنَا أَحْمَدُ بْنُ إِبْرَاهِيمَ الدَّوْرَقِيُّ، حَدَّثَنَا هُشَيْمٌ، عَنِ ابْنِ أَبِي لَيْلَى، عَنْ حُمَيْضَةَ بِنْتِ الشَّمَرْدَلِ، عَنْ قَيْسِ بْنِ الْحَارِثِ، قَالَ أَسْلَمْتُ وَعِنْدِي ثَمَانِ نِسْوَةٍ فَأَتَيْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ فَقُلْتُ ذَلِكَ لَهُ فَقَالَ " اخْتَرْ مِنْهُنَّ أَرْبَعًا " .
