(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 Meditate upon the name of your Lord morning and evening; 25 and in the night prostrate to Him; and exalt Him for a long night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 This surely is a reminder: Therefore whosoever desires may take the way to 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
