Establish prayer at the decline of the sun [from its meridian] until the darkness of the night and [also] the Qur'an of dawn. Indeed, the recitation of dawn is ever witnessed. 78 And of the night - keep the vigil therein, as an act of supererogation for thee; belike thy Lord will raise thee up in a station praised. 79 (Muhammad), say, "Lord, make me enter through a path that will lead to the Truth and come out of an exit that will take me to the Truth. Give me helpful authority. 80 And say: 'The truth has come, and falsehood has vanished away; surely falsehood is ever certain to vanish.' 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 And when We bless man, he turns away, and withdraws aside; but when evil visits him, he is in despair. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
