Sayyiduna Abu Musa (may Allah be pleased with him) narrates that I and my two cousins went to the service of the Prophet (peace and blessings be upon him). One of them said: O Messenger of Allah! Appoint me as a leader over any of the tasks that Allah has entrusted to you. The other also said the same. The Prophet (peace and blessings be upon him) said: We do not appoint to this work anyone who asks for it or desires it.
