Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 Remember the name of thy Lord at morn and evening. 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 desire except as God wills. Verily He is all-knowing and all-wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
