Surely We have sent down the Koran on thee, a sending down; 23 So wait patiently for the command of your Lord and do not yield to any sinful or disbelieving person among them (people). 24 And remember the Name of thy Lord at dawn and in the evening 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
