It is narrated from Sayyiduna Hamzah Aslami that once the Prophet (peace and blessings be upon him) appointed him as the leader of a detachment. When I was about to depart, the Prophet (peace and blessings be upon him) said: If you succeed in capturing such-and-such person, then burn him in the fire. When I turned my back, the Prophet (peace and blessings be upon him) called me and said: If you find him, then only kill him (do not burn him in the fire), because only the Lord of the Fire can punish with fire.
