Hazrat Ali (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) sent a detachment and appointed a man from the Ansar as their leader, and ordered the people to obey him. Then the leader became angry with the people and said, "Did the Prophet (peace and blessings be upon him) not order you to obey me?" The people replied, "Indeed, he did." Upon this, he said, "I order you to gather wood and light a fire with it, and then jump into it." The people gathered wood and lit the fire. When they were about to jump in, they began to look at one another, and some among them said, "We followed the Prophet (peace and blessings be upon him) only to save ourselves from the fire. Should we then enter it ourselves?" Meanwhile, the fire cooled down and the leader's anger subsided. Later, when this was mentioned to the Prophet (peace and blessings be upon him), he said, "If they had jumped into it, they would never have come out of it. Obedience is only in good matters."
