حَدَّثَنَا مَحْمُودُ بْنُ خَالِدٍ، حَدَّثَنَا مُحَمَّدُ بْنُ عَائِذٍ، حَدَّثَنَا الْوَلِيدُ، حَدَّثَنَا عِيسَى بْنُ يُونُسَ، حَدَّثَنِي فِيمَا، حَدَّثَهُ ابْنٌ لِعَدِيِّ بْنِ عَدِيٍّ الْكِنْدِيِّ، أَنَّ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ، كَتَبَ إِنَّ مَنْ سَأَلَ عَنْ مَوَاضِعِ الْفَىْءِ، فَهُوَ مَا حَكَمَ فِيهِ عُمَرُ بْنُ الْخَطَّابِ رضى الله عنه فَرَآهُ الْمُؤْمِنُونَ عَدْلاً مُوَافِقًا لِقَوْلِ النَّبِيِّ صلى الله عليه وسلم ‏"‏ جَعَلَ اللَّهُ الْحَقَّ عَلَى لِسَانِ عُمَرَ وَقَلْبِهِ ‏"‏ ‏.‏ فَرَضَ الأَعْطِيَةَ وَعَقَدَ لأَهْلِ الأَدْيَانِ ذِمَّةً بِمَا فُرِضَ عَلَيْهِمْ مِنَ الْجِزْيَةِ لَمْ يَضْرِبْ فِيهَا بِخُمُسٍ وَلاَ مَغْنَمٍ ‏.‏

Narrated Umar ibn al-Khattab: A son of Adi ibn Adi al-Kindi said that Umar ibn AbdulAziz wrote (to his governors): If anyone asks about the places where spoils (fay') should be spent, that should be done in accordance with the decision made by Umar ibn al-Khattab (Allah be pleased with him). The believers considered him to be just, according to the saying of the Prophet (PBUH): Allah has placed truth upon Umar's tongue and heart. He fixed stipends for Muslims, and provided protection for the people of other religions by levying jizyah (poll-tax) on them, deducting no fifth from it, nor taking it as booty.
