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 Mention the Name of your Lord, mornings and evenings. 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
