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, "Lord, grant me an honourable entrance and an honourable exit, and sustain me with Your power." 80 And say thou: the truth is come, and falsehood hath vanished; verily falsehood is ever vanishing. 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 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
