We have indeed, sent down to you the Koran, a (clear) sending, 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 Mention the Name of your Lord, mornings and evenings. 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 This is a reminder. Let whoever wishes, take the right path to his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
