وَعَنِ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا
قَالَ: «نَهَى عُمَرُ عَنْ بَيْعِ أُمَّهَاتِ اَلْأَوْلَادِ فَقَالَ: لَا تُبَاعُ، وَلَا تُوهَبُ، وَلَا تُورَثُ، لِيَسْتَمْتِعْ بِهَا مَا بَدَا لَهُ، فَإِذَا مَاتَ فَهِيَ حُرَّةٌ»
Umar (radiyallahu anhu) forbade the sale of the slave-women who have given birth to children (of their owners). He said, “She is not to be sold, bestowed as a gift or inherited. He (the owner) enjoys her as long as he lives and when he dies, she becomes free.”.
