(O Prophet), indeed We have revealed the Qur'an to you in portions. 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 prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Surely these love the transitory and neglect a grievous day before 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 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
