وَحَدَّثَنِي وَحَدَّثَنِي مَالِك أَنَّهُ بَلَغَهُ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ " أَتَتْهُ وَلِيدَةٌ قَدْ ضَرَبَهَا سَيِّدُهَا بِنَارٍ أَوْ أَصَابَهَا بِهَا، فَأَعْتَقَهَا " .
A slave girl was brought to Sayyiduna Umar bin Khattab (may Allah be pleased with him) whose master had burned her with fire, so he (may Allah be pleased with him) set her free.
