Chapter 20: Tribute, Spoils, and Rulership (Kitab Al-Kharaj, Wal-Fai' Wal-Imarah)
Narrated Abu Musa: I went along with two men to see the Prophet (ﷺ). One of them recited tashahhud and said: We have come to you so that you may employ us for your work. The other also said the same thing. He (the Prophet) replied: The most faithless of you in our eyes is the one who asked for it (responsible post). Abu Musa then apologized to the Prophet (ﷺ) and said: I did not know why they came to you. He did not employ them for anything until he died.
