It is We Who have sent down the Qur'an to thee by stages. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 Mention the Name of your Lord, mornings and evenings. 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 We have created them and strengthened their forms, and when We will, We can change their likenesses with [complete] alteration. 28 This chapter is a reminder. Let those who want, seek guidance from their Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
