Tribute, Spoils, and Rulership (Kitab Al-Kharaj, Wal-Fai' Wal-Imarah)
Dawud :: Book 19 : Hadith 2948
Narrated Jabir ibn Abdullah:
The Prophet (peace_be_upon_him) said: I am nearer to the believers than themselves, so if anyone leaves property, it goes to his heirs, and if anyone leaves debt and dependants, let the matter come to me and I shall be responsible.
