(Muhammad), We have revealed the Quran to you in gradual steps. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 Remember the name of thy Lord at morn 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 We have created them and strengthened their forms, and when We will, We can change their likenesses with [complete] alteration. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
