(Muhammad), We have revealed the Quran to you in gradual steps. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 Meditate upon the name of your Lord morning and evening; 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
