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 as for the night, keep vigil a part of it, as a work of supererogation for thee; it may be that thy Lord will raise thee up to a laudable station. 79 And say: 'My Lord, lead me in with a just ingoing, and lead me out with a just outgoing; grant me authority from Thee, to help me.' 80 And say: Truth hath come and falsehood hath vanished away. Lo! 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 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: Every one acts according to his manner; but your Lord best knows who is best guided in the path. 84
