Muwatta Imam Malik Book of Setting Free and Wala', Hadith 14

Malik related to me that Yahya ibn Said said, ''Abd ar-Rahman ibn Abi Bakr died in his sleep, and A'isha, the wife of the Prophet ﷺ set free many slaves for him." Malik said, "This is what I like best of what I have heard on the subject."

وَحَدَّثَنِي مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّهُ قَالَ تُوُفِّيَ عَبْدُ الرَّحْمَنِ بْنُ أَبِي بَكْرٍ فِي نَوْمٍ نَامَهُ فَأَعْتَقَتْ عَنْهُ عَائِشَةُ زَوْجُ النَّبِيِّ ﷺ رِقَابًا كَثِيرَةً . قَالَ مَالِكٌ وَهَذَا أَحَبُّ مَا سَمِعْتُ إِلَىَّ فِي ذَلِكَ .
