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."

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 ‏.‏
