(O Prophet), indeed We have revealed the Qur'an to you 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 Remember the name of thy Lord at morn and evening. 25 And during the night prostrate to Him and exalt 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 an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
