Narrated Ibn `Umar: That he was in the company of the Prophet on a journey, riding a troublesome camel belonging to `Umar. The camel used to go ahead of the Prophet, so Ibn `Umar's father would say, "O `Abdullah! No one should go ahead of the Prophet." The Prophet said to him, "Sell it to me." `Umar said to the Prophet "It is for you." So, he bought it and said, "O `Abdullah! It is for you, and you can do with it what you like."

Narrated Ibn 'Umar (ra): We were accompanying the Prophet (saws) on a journey and I was riding an unmanageable camel belonging to 'Umar (ra), and I could not bring it under my control. So, it used to go ahead of the party and 'Umar would check it and force it to retreat, and again it went ahead and again 'Umar forced it to retreat. The Prophet (saws) asked 'Umar to sell that camel to him. 'Umar replied, "It is for you O Allah's Messenger!" Allah's Messenger (saws) told 'Umar to sell that camel to him (not to give it as gift). So, 'Umar sold it to Allah's Messenger (saws). Then the Prophet (saws) said to 'Abdullah bin 'Umar "This camel is for you O 'Abdullah (as a present) and you could do with it whatever you like."
