Then rejoice in the bargain which you have concluded: that is the achievement supreme.;
112. Those that turn (to Allah) in repentance; that served Him, and praise Him; that wander in devotion to the Cause of Allah; that bow down and prostrate themselves in prayer; that enjoin good and forbid evil; and observed the limit set by Allah – (these do rejoice). So proclaim the glad tiding to the believers.;
