Once Umar (radiyallahu ‘anhu) and his son Abdullah ibn Umar (radiyallahu ‘anhu) were riding with the Prophet (sallallahu alayhi wasallam). Abdullah had a camel (owned by his father) that was naturally very fast, and it kept crossing the camel of the Prophet and going beyond it, no matter how much Abdullah tried to hold it back.
At one point, Umar (ra) got really mad at him and said, “Ya Abdullah! No one should go in front of the Prophet! Move your camel!” Abdullah kept struggling with his camel and Rasulullah (Sm.) could see that Abdullah was hurt, because his father had put him down in front of the Prophet (Sm).
So all of a sudden Rasulullah (Sm) stopped, went to Umar (who owned the camel his son was riding) and said, “Sell it to me.” Umar (ra) tried to give it to him as a gift but Rasulullah (Sm) insisted and paid for the camel and bought it.
Then the Prophet (Sm) took the camel, gave it to Abdullah and told him, “This is for you, Abdullah. Do as you wish with it.” (Meaning he was giving him permission to go infront of him.)

This story is way too beautiful, Subhanallah! The love and care of the Prophet (Sm) for Ibn Umar just makes me smile in awe!
