We have revealed the Qur'an to you gradually; 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And remember thou the name of thy Lord in the morning and in the evening. 25 And during part of the night adore Him, and give glory to Him (a) long (part of the) 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 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 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
