Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 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 bear in mind thy Sustainer's name at morn and evening 25 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Verily those love the herein, and leave in front of them a heavy 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 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
