Truly successful are the believers who are humble in their prayers; who avoid profanity, and are active in charitable works; who restrain their carnal desires, except with their wives and slave-girls for these are lawful to them but whoever seeks after more than that has transgressed; who are true to their trusts and promises and never neglect their prayers. These are the inheritors; who shall inherit the Paradise, and therein they shall abide forever.

(23:1-11)
