Observe the service of prayer from the sun's declining from the meridian to the darkening of the night, and the recitation at dawn. Indeed the Recitation at dawn is palpably evident. 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 And say thou: O my Lord! cause me to enter a rightful entrance and cause me to go forth with a rightful outgoing, and appoint for me from before Thee an authority helpful. 80 And say: The truth has come and the falsehood has vanished; surely falsehood is a vanishing (thing). 81 And We send down, of the Koran, that which is a healing and a mercy to the believers; and the unbelievers it increases not, except in loss. 82 And when We bestow Our Grace on man (the disbeliever), he turns away and becomes arrogant, far away from the Right Path. And when evil touches him he is in great despair. 83 Say, (O Prophet): "Each one acts according to his own manner. Your Lord knows well who is best-guided to the Right Path." 84
