We have indeed, sent down to you the Koran, a (clear) sending, 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 and remember the name of your Lord, morning and evening; 25 And during the night - worship Him; and hallow Him the livelong night. 26 Indeed, these [disbelievers] love the immediate and leave behind them a grave Day. 27 We have created them and have given them strength. Had We wanted, We could have replaced them with another people like them. 28 This chapter is a reminder. Let those who want, seek guidance from their Lord. 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
