Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 Await, then, in all patience thy Sustainer's judgment, and pay no heed to any of them, who is a wilful sinner or an ingrate; 24 And glorify the name of your Lord morning and evening. 25 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put 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 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
