Who will be the owner of great happiness in this world and in the Hereafter?

 

Verses 33-35 of Chapter 41

Who is better in speech than one who calls (men) to Allah, works righteousness, and says, “I am of those who bow in Islam”? The good deed and the evil deed are not alike. Repel the evil deed with one which is better, then lo! he, between whom and thee there was enmity (will become) as though he was a bosom friend. But none is granted it save those who are steadfast, and none is granted it save the owner of great happiness.
