وَعَنْ جَابِرٍ رضى الله عنه
قَالَ: «كُنَّا نَبِيعُ سَرَارِيَنَا، أُمَّهَاتِ اَلْأَوْلَادِ، وَالنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حَيٌّ، لَا نَرَى بِذَلِكَ بَأْسًا»
We used to sell our slave-women who had borne (our) children while the Prophet (sallallahu alayhi wa sallam) was still living, and he saw no harm in that.
