We have revealed the Qur'an to you gradually; 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 and glorify your Lord morning and evening; 25 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Indeed, these [disbelievers] love the immediate and leave behind them a grave Day. 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 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
