Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates that once the Prophet (peace and blessings be upon him) camped at a place and went to relieve himself. When he returned, he saw that someone had set fire to an anthill on the ground or on a tree. The Prophet (peace and blessings be upon him) asked, "Who has done this?" A man replied, "O Messenger of Allah (peace and blessings be upon him)! I did it." He said, "Extinguish this fire, extinguish this fire."
