Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 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 thy Lord at dawn and in the evening 25 Prostrate before Him and glorify Him extensively during 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 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, 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
