Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 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 the Name of your Lord at the dawn and in the evening; 25 and during the night prostrate ourself before Him, and extol His glory for 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 strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
