Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 24 And celebrate the name of thy Lord morning and evening, 25 and in the night prostrate to Him; and exalt Him for a long 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, but, when We will, We shall indeed exchange their likes. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
