Narrated `Ali: The Prophet , sent an army and appointed some man their commander The man made a fire and then said (to the soldiers), "Enter it." Some of them intended to enter it while some others said, 'We have run away from it (i.e., embraced Islam to save ourselves from the 'fire')." They mentioned that to the Prophet, and he said about people who had intended to enter the fire. ''If they had entered it, they would have remained In it till the Day of Resurrection.'' Then he said to others, "No obedience for evil deeds, obedience is required only in what is good ."

Narrated `Ali: The Prophet sent a Sariya under the command of a man from the Ansar and ordered the soldiers to obey him. He (i.e. the commander) became angry and said "Didn't the Prophet order you to obey me!" They replied, "Yes." He said, "Collect fire-wood for me." So they collected it. He said, "Make a fire." When they made it, he said, "Enter it (i.e. the fire)." So they intended to do that and started holding each other and saying, "We run towards (i.e. take refuge with) the Prophet from the fire." They kept on saying that till the fire was extinguished and the anger of the commander abated. When that news reached the Prophet he said, "If they had entered it (i.e. the fire), they would not have come out of it till the Day of Resurrection. Obedience (to somebody) is required when he enjoins what is good."

Narrated `Ali: The Prophet sent an army unit (for some campaign) and appointed a man from the Ansar as its commander and ordered them (the soldiers) to obey him. (During the campaign) he became angry with them and said, "Didn't the Prophet order you to obey me?" They said, "Yes." He said, "I order you to collect wood and make a fire and then throw yourselves into it." So they collected wood and made a fire, but when they were about to throw themselves into, it they started looking at each other, and some of them said, "We followed the Prophet to escape from the fire. How should we enter it now?" So while they were in that state, the fire extinguished and their commander's anger abated. The event was mentioned to the Prophet and he said, "If they had entered it (the fire) they would never have come out of it, for obedience is required only in what is good." (See Hadith No. 629. Vol. 5)
