(31) "For those who believe and work righteousness, is (every) blessedness, and a beautiful place of (final) return."

(32) But those who believe and work righteousness will be admitted to gardens beneath which rivers flow,- to dwell therein for aye with the leave of their Lord. Their greeting therein will be: "Peace!"

(33) Whoever works righteousness, man or woman, and has Faith, verily, to him will We give a new Life, a life that is good and pure and We will bestow on such their reward according to the best of their actions.

(34) Verily this Qur'an doth guide to that which is most right (or stable), and giveth the Glad Tidings to the Believers who work deeds of righteousness, that they shall have a magnificent reward;

(35) Your Lord knoweth best what is in your hearts: If ye do deeds of righteousness, verily He is Most Forgiving to those who turn to Him again and again (in true penitence).

(36) As to those who believe and work righteousness, verily We shall not suffer to perish the reward of any who do a (single) righteous deed.

(37) "But whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command."

(38) Say: "I am but a man like yourselves, (but) the inspiration has come to me, that your Allah is one Allah: whoever expects to meet his Lord, let him work righteousness, and, in the worship of his Lord, admit no one as partner.

(39) Except those who repent and believe, and work righteousness: for these will enter the Garden and will not be wronged in the least,-

(40) On those who believe and work deeds of righteousness, will (Allah) Most Gracious bestow love.
