Establish regular prayers - at the sun's decline till the darkness of the night, and the morning prayer and reading: for the prayer and reading in the morning carry their testimony. 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 thou: O my Lord! cause me to enter a rightful entrance and cause me to go forth with a rightful outgoing, and appoint for me from before Thee an authority helpful. 80 Say, "Truth has come and falsehood has disappeared. Falsehood is always bound to wither away." 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 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 does as he wants. Your Lord knows best who has the right guidance." 84
