(Muhammad), We have revealed the Quran to you in gradual steps. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 and glorify your Lord morning and evening; 25 And during the night - worship Him; and hallow Him the livelong night. 26 Indeed, these [disbelievers] love the immediate and leave behind them a grave Day. 27 It is We Who created them, and We have made them of strong built. And when We will, We can replace them with others like them with a complete replacement. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 But you cannot will it unless God wills [to show you that way]: for, behold, God is indeed all-seeing, wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
