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 yourself before Him at night, and extol His Glory during the long watches of the night. 26 Surely these love the transitory and neglect a grievous day before them. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
