Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrates: We went to the service of the Prophet Muhammad (peace and blessings be upon him) to ask him for a riding animal. Some white-humped camels were presented to the Prophet (peace and blessings be upon him). We said: O Messenger of Allah! Please give us for riding. So the Prophet (peace and blessings be upon him) swore that he would not give us an animal for riding. Then some other camels were presented to the Prophet (peace and blessings be upon him). We said: O Messenger of Allah! Please give us for our riding. So the Prophet (peace and blessings be upon him) gave us for riding. When we returned from there, we thought, what have we done? Did we not draw the Prophet’s (peace and blessings be upon him) attention to his oath? Then we went to the Prophet (peace and blessings be upon him) and mentioned this matter to him. The Prophet (peace and blessings be upon him) said:“Whenever I take an oath and then consider something else better than it, I will do what is better and will offer expiation for my oath.”
