Verily We! it is We Who have revealed unto thee the Qur'an, 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 celebrate the name of thy Lord morning and evening, 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 As to these, they love the fleeting life, and put away behind them a 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 is indeed an advice; so whoever wishes may take the path towards his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
