We have revealed the Qur'an to you gradually; 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 Remember the name of thy Lord at morn and evening. 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
