Establish the prayer at the decline of the sun till the darkening of the night and the Koran recital at dawn. Surely, the Koran recital at dawn is witnessed. 78 And during the night wake up and pray, as an additional prayer: it may well be that your Lord will raise you to a station of praise and glory." 79 Say: 'Lord, grant me an entrance of sincerity and an exit of sincerity, and give me from Yours a victorious power' 80 And say thou: the truth is come, and falsehood hath vanished; verily falsehood is ever vanishing. 81 And We send down from the Quran that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zalimun (polytheists and wrong-doers) nothing but loss. 82 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 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
