What was the task that Allah's Apostle (peace be upon him) appointed Ibn Al-Lutbiya from the tribe of Al-Asd to do?
 Narrated Abu Humaid Al-Sa`idi:                     Allah's Apostle (p.b.u.h) appointed a man called Ibn Al-Lutbiya, from the tribe of Al-Asd to collect Zakat from Bani Sulaim. When he returned, (after collecting the Zakat) the Prophet checked the account with him.
