The Prophet....

A man came to the Prophet Muhammad (peace and blessings of Allah be upon him) complaining that his heart was hard.

The Prophet (peace and blessingsof Allah be upon him) said to him,  

“Would you like 

your heart to become soft 

and to get what you want? 

Say have mercy to the orphan, pat his head, 

feed him from your own food, and
your heart will become soft and 

you will get what you want.”
