Perform the prayer at the sinking of the sun to the darkening of the night and the recital of dawn; surely the recital of dawn is witnessed. 78 As for the night there is a voluntary deed for you to keep vigil in part it. Perhaps your Lord will raise you to a praiseworthy station. 79 Say, "Lord, grant me an honourable entrance and an honourable exit, and sustain me with Your power." 80 And say: The truth has come and the falsehood has vanished; surely falsehood is a vanishing (thing). 81 And We send down, of the Koran, that which is a healing and a mercy to the believers; and the unbelievers it increases not, except in loss. 82 When We bestow a favour upon a person, he turns his back and draws aside; and when evil afflicts him he gives himself up to despair. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
