Keep the prayer established, from the declining of the sun until darkness of the night, and the Qur’an at dawn; indeed the angels witness the reading of the Qur’an at dawn. 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 Say: 'Lord, grant me an entrance of sincerity and an exit of sincerity, and give me from Yours a victorious power' 80 And proclaim: "The Truth has come, and falsehood has vanished. Surely falsehood is ever bound to vanish." 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 And when We bestow favor on man, he turns aside and behaves proudly, and when evil afflicts him, he is despairing. 83 Say: Every one acts according to his manner; but your Lord best knows who is best guided in the path. 84
