“We used to sell our slave women and the mothers of our children (Umahat Awaldina) when the Prophet ﷺ was still living among us, and we did not see anything wrong with that.” (Using translation from Ibn Mājah 2517)
أَنَّهُ سَمِعَ جَابِرًا يَقُولُ «كُنَّا نَبِيعُ سَرَارِيَّنَا أُمَّهَاتِ الْأَوْلَادِ وَالنَّبِيُّ ﷺ حَيٌّ مَا نَرَى بِذَلِكَ بَأْسًا»
