Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 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 thy Lord at dawn and in the evening 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
