Surely We Ourselves have revealed the Quran to you revealing (it) 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 Remember the name of thy Lord at morn and evening. 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
