(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 And remember the Name of thy Lord at dawn and in the evening 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 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 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
