Narrated Maimuna, the wife of the Prophet ﷺ that she manumitted her slave-girl and the Prophet ﷺ said to her, "You would have got more reward if you had given the slave-girl to one of your maternal uncles."
إِنَّ مَيْمُونَةَ زَوْجَ النَّبِيِّ ﷺ أَعْتَقَتْ وَلِيدَةً لَهَا فَقَالَ لَهَا: «وَلَوْ وَصَلْتِ بَعْضَ أَخْوَالِكِ كَانَ أَعْظَمَ لأَجْرِكِ۔»
