[Machine] Ghaylan bin Salamah al-Thaqafi converted to Islam, and he had ten wives. The Messenger of Allah ﷺ instructed him to choose four of them and leave the rest. This is how I found the hadith reported by the people of Yamamah from Ma'mar.
أَسْلَمَ غَيْلَانُ بْنُ سَلَمَةَ الثَّقَفِيُّ وَلَهُ عَشْرُ نِسْوَةٍ «فَأَمَرَهُ رَسُولُ اللَّهِ ﷺ أَنْ يَتَخَيَّرَ مِنْهُنَّ أَرْبَعًا وَيَتْرُكَ سَائِرَهُنَّ» وَهَكَذَا وَجَدْتُ الْحَدِيثَ عِنْدَ أَهْلِ الْيَمَامَةِ عَنْ مَعْمَرٍ
