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 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 Say: "O my Lord! Let my entry be by the Gate of Truth and Honour, and likewise my exit by the Gate of Truth and Honour; and grant me from Thy Presence an authority to aid (me)." 80 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 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, (O Prophet): "Each one acts according to his own manner. Your Lord knows well who is best-guided to the Right Path." 84
