Umar on Slaves: A slave injured by their master must be set free

Malik reported: Umar ibn al-Khattab, may Allah be pleased with him, was presented with a servant woman who had been struck by her master with a piece of fire or had been injured by it, so he ordered him to emancipate her.

Al-Shawkani said, “Malik, Al-Awza’i, and Al-Layth adhered to the opinion that a slave is freed on account of that abuse, he will have his loyalty inheritance, and the authorities will punish the master for what he did.”

عن مالك أَنَّ عُمَرَ بْنَ الْخَطَّابِ رضي الله عنه أَتَتْهُ وَلِيدَةٌ قَدْ ضَرَبَهَا سَيِّدُهَا بِنَارٍ أَوْ أَصَابَهَا بِهَا فَأَعْتَقَهَا
