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! Cause me to come in with a firm incoming and to go out with a firm outgoing. And give me from Thy presence a sustaining Power. 80 And proclaim, “The Truth has arrived and falsehood has vanished; indeed falsehood had to vanish.” (* With the arrival of the Last Prophet – Mohammed peace and blessings be upon him) 81 THUS, step by step, We bestow from on high through this Qur'an all that gives health [to the spirit] and is a grace unto those who believe [in Us,] the while it only adds to the ruin of evildoers: 82 When We are gracious to man he turns away and moves aside; yet when evil befalls him he begins to despair. 83 Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
