«لست أنا حملتكم ولكن الله حملكم وإني والله إن شاء الله لا أحلف على يمين فأرى غيرها خيرا منها إلا أتيت الذي هوخير وتحللتها»
The Prophet (peace and blessings be upon him) said:
"It is not I who gave you mounts; rather, it is Allah who gave you mounts. And by Allah, if Allah wills, whenever I swear an oath and then see something else better than it, I do that which is better and make expiation for my oath."
