Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 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 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 creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 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 is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
