عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ يُوَدَّى الْمُكَاتَبُ بِقَدْرِ مَا أَدَّى
It is narrated from Sayyiduna Ali bin Abi Talib, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him and his family, said: A mukatab (contracted slave) will be given blood money in proportion to the amount he has paid.
