Keep up prayer from the declining of the sun till the darkness of the night and the morning recitation; surely the morning recitation is witnessed. 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 entrance of sincerity and an exit of sincerity, and give me from Yours a victorious power' 80 And say: The truth has come and the falsehood has vanished; surely falsehood is a vanishing (thing). 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, "Everyone does as he wants. Your Lord knows best who has the right guidance." 84
