Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 and glorify your Lord morning and evening; 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long 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 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
