It is We Who have sent down the Qur'an to thee by stages. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever 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 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 This chapter is a reminder. Let those who want, seek guidance from their Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
