Truly, it is We who have revealed to you the Quran, a gradual revelation. 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 during the night - worship Him; and hallow Him the livelong night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 28 Verily! This (Verses of the Quran) is an admonition, so whosoever wills, let him take a Path to his Lord (Allah). 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
