Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 And remember thou the name of thy Lord in the morning and in the evening. 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 It is We Who created them, and We have made their joints strong; but, when We will, We can substitute the like of them by a complete change. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
