Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 And celebrate the name of thy Lord morning and evening, 25 And during the night - worship Him; and hallow Him the livelong night. 26 Surely these love the transitory and neglect a grievous day before 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 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But you will not unless God wills; surely God 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
