The Prophet (peace and blessings of Allah be upon him) used to say "don't be angry and will be rewarded with Paradise" 

"A man came to the Prophet (peace and blessings of Allah be upon him) and said : O Messenger of God who are the people that Allah loves the most?

And what deeds does God love most?"

The Prophet (peace and blessings of Allah be upon him) replied :

"Those God loves most are the most useful ones to people, and the deeds God loves most is making a Muslim happy"
