Tribute, Spoils, and Rulership (Kitab Al-Kharaj, Wal-Fai' Wal-Imarah)
Dawud :: Book 19 : Hadith 2984
Narrated Mujja'ah ibn Mirarah al-Yamani:
Mujja'ah went to the Prophet (peace_be_upon_him) asking him for the blood-money of his brother whom Banu Sadus from Banu Dhuhl had killed.
The Prophet (peace_be_upon_him) said: Had I appointed blood-money for a polytheist, I should have appointed it for your brother. But I shall give you compensation for him. So the Prophet (peace_be_upon_him) wrote (a document) for him that he should be given a hundred camels which were to be acquired from the fifth taken from the polytheists of Banu Dhuhl. So he took a part of them, for Banu Dhuhl embraced Islam.
He then asked AbuBakr for them later on, and brought to him the document of the Prophet (peace_be_upon_him). So AbuBakr wrote for him that he should be given one thousand two hundred sa's from the sadaqah of al-Yamamah; four thousand (sa's) of wheat, four thousand (sa's) of barley, and four thousand (sa's) of dates.
The text of the document written by the Prophet (peace_be_upon_him) for Mujja'ah was as follows: "In the name of Allah, the Beneficent, the Merciful. This document is from Muhammad, the Prophet, to Mujja'ah ibn Mirarah of Banu Sulma. I have given him one hundred camels from the first fifth acquired from the polytheist of Banu Dhuhl as a compensation for his brother."
