(O Prophet), indeed We have revealed the Qur'an to you 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 thy Lord at dawn and in the evening 25 And during the night - worship Him; and hallow Him the livelong night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He admits whosoever He will to His benevolence. But for the evil-doers He has prepared a painful punishment. 31
