Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 23 Therefore stay patient upon your Lord’s command, and do not listen to any of the sinners or ingrates among them. 24 Remember the name of thy Lord at morn and evening. 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Verily those love the herein, and leave in front of them a heavy day. 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 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He maketh whomsoever He listeth to enter His mercy. And the wrong-doers! for them He hath gotten ready a torment afflective. 31
