It is We Who have sent down the Qur'an to thee by stages. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 Remember the name of thy Lord at morn and evening. 25 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
