"Ghilan bin Salamah Ath-Thaqafi accepted Islam and he had ten wives in Jahiliyyah who accepted Islam along with him. So the Prophet ordered (him) to chose four (of them)." (Using translation from Tirmidhī 1128)
أَسْلَمَ غَيْلَانُ بْنُ سَلَمَةَ الثَّقَفِيُّ وَتَحْتَهُ عَشَرُ نِسْوَةٍ فِي الْجَاهِلِيَّةِ وَأَسْلَمْنَ مَعَهُ فَأَمَرَهُ النَّبِيُّ ﷺ أَنْ يَخْتَارَ مِنْهُنَّ أَرْبَعًا
