Say your prayer when the sun declines until the darkness of night and also at dawn. Dawn is certainly witnessed (by the angels of the night and day). 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 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 proclaim: "The Truth has come, and falsehood has vanished. Surely falsehood is ever bound to vanish." 81 And We send down of the Qur'an that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss. 82 When We do favors to the human being, he disregards it and turns away from it. When evil afflicts him, he becomes despairing. 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
