(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And remember thou the name of thy Lord in the morning and in the evening. 25 And bow in homage part of the night, and glorify Him far into the night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them and made firm their make, and when We please We will bring in their place the likes of them by a change. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
