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 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 And pray: "My Lord! Cause me to enter wherever it be, with Truth, and cause me to exit, wherever it be, with Truth, and support me with authority from Yourself." 80 And say: "The truth has now come [to light,] and falsehood has withered away: for, behold, all falsehood is bound to wither away!" 81 We send down in the Quran that which is healing and a mercy to those who believe; as for the evil-doers, it only increases their loss. 82 When We are gracious to man he turns away and moves aside; yet when evil befalls him he begins to despair. 83 Say to them, "Everyone acts in his own way, and your Lord knows best who is rightly guided." 84
