We have revealed the Qur'an to you gradually; 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And, remember the Name of your Lord at the dawn and in the evening; 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 It is We Who created them, and We have made their joints strong; but, when We will, We can substitute the like of them by a complete change. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He maketh whomsoever He listeth to enter His mercy. And the wrong-doers! for them He hath gotten ready a torment afflective. 31
