Observe the service of prayer from the sun's declining from the meridian to the darkening of the night, and the recitation at dawn. Indeed the Recitation at dawn is palpably evident. 78 And as for the night, keep vigil a part of it, as a work of supererogation for thee; it may be that thy Lord will raise thee up to a laudable station. 79 And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority." 80 And say thou: the truth is come, and falsehood hath vanished; verily falsehood is ever vanishing. 81 And We reveal of the Quran that which is a healing and a mercy to the believers, and it adds only to the perdition of the unjust. 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: "Everyone acts according to his own disposition: But your Lord knows best who it is that is best guided on the Way." 84
