In this Hadīth, Abu Mūsa (may Allah be pleased with him) went to the Prophet (may Allah's peace and blessings be upon him) with two men from his own tribe. The two men asked for employment as governors, so the Prophet (may Allah's peace and blessings be upon him) said that he would not give a position of power to anyone who asks for it. When someone seeks a position, he is left to it and is not given support by Allah. The Prophet (may Allah's peace and blessings be upon him) rather, sent Abu Mūsa to govern Yemen and then asked Mu‘ādh to reach him there. Mu‘ādh found a fettered man in the presence of Abu Mūsa. This man converted from Judaism to Islam and then back to Judaism. So, Mu‘ādh said that the due punishment must be inflicted on him, i.e., the punishment for apostasy which is capital punishment. Thus the man was killed. Both Abu Mūsa and Mu‘ādh then talked about voluntary night prayer. One of them said that he sleeps and prays, and hopes that he would receive reward for his sleep just as he receives reward for his prayer.
