Keep up prayer from the declining of the sun till the darkness of the night and the morning recitation; surely the morning recitation is witnessed. 78 And rise from thy sleep and pray during part of the night [as well,] as a free offering from thee, and thy Sustainer may well raise thee to a glorious station [in the life to come]. 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: "Truth has (now) arrived, and Falsehood perished: for Falsehood is (by its nature) bound to perish." 81 We reveal the Quran which is a cure and mercy for the believers but does nothing for the unjust except to lead them to perdition. 82 And when We bestow favor upon the disbeliever, he turns away and distances himself; and when evil touches him, he is ever despairing. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
