Sunan Ibn Majah 1953
The Chapters on Marriage
A man became Muslim and he has more than four wives
حَدَّثَنَا يَحْيَى بْنُ حَكِيمٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، قَالَ أَسْلَمَ غَيْلاَنُ بْنُ سَلَمَةَ وَتَحْتَهُ عَشْرُ نِسْوَةٍ فَقَالَ لَهُ النَّبِيُّ ـ صلى الله عليه وسلم ـ خُذْ مِنْهُنَّ أَرْبَعًا .
It was narrated that Ibn 'Umar said: “Ghailan bin Salamah became Muslim and he had ten wives. The Prophet (ﷺ) said to him: 'Choose four of them.' ”
