We have revealed the Qur'an to you gradually; 23 Therefore be patient (O Muhammad SAW) and submit to the Command of your Lord (Allah, by doing your duty to Him and by conveying His Message to mankind), and obey neither a sinner nor a disbeliever among them. 24 And remember the name of your Lord morning and evening. 25 Prostrate before Him and glorify Him extensively during the night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 It is We Who created them, and We have made them of strong built. And when We will, We can replace them with others like them with a complete replacement. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
