Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 and remember the name of your Lord, morning and evening; 25 And during the night - worship Him; and hallow Him the livelong night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
