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 a part of the night, pray Tahajjud beyond what is incumbent on you; maybe your Lord will raise you to a position of great glory. 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 Say, "Truth has come and falsehood has disappeared. Falsehood is always bound to wither away." 81 And We reveal of the Quran that which is a healing and a mercy to the believers, and it adds only to the perdition of the unjust. 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, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
