(Muhammad), We have revealed the Quran to you in gradual steps. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And mention the name of your Lord [in prayer] morning and evening 25 And during the night - worship Him; and hallow Him the livelong night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy Day. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
