Muwatta Malik #1144
Fara'id
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ إِسْمَاعِيلَ بْنِ أَبِي حَكِيمٍ، أَنَّ نَصْرَانِيًّا، أَعْتَقَهُ عُمَرُ بْنُ عَبْدِ الْعَزِيزِ هَلَكَ - قَالَ إِسْمَاعِيلُ - فَأَمَرَنِي عُمَرُ بْنُ عَبْدِ الْعَزِيزِ أَنْ أَجْعَلَ مَالَهُ فِي بَيْتِ الْمَالِ .
Yahya related to me from Malik from Yahya ibn Said from Ismail
ibn Abi Hakim that Umar ibn Abd al-Aziz freed a christian who then
died. Ismail said, ''Umar ibn Abd al-Aziz ordered me to put his
property in the bayt al-mal."
