We have revealed the Qur'an to you gradually; 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 and remember the name of your Lord, morning and evening; 25 and part of the night; bow down before Him and magnify Him through the long 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 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
