Here is the translation of the verses:

This was Our tradition with Our Messengers who lived before you, and you will find no change in Our tradition. (77)

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)

Say your special (tahajjud) prayer during some part of the night as an additional (obligatory) prayer for you alone so that perhaps your Lord will raise you to a highly praiseworthy position. (79)

(Muhammad), say, "Lord, make me enter through a path that will lead to the Truth and come out of an exit that will take me to the Truth. Give me helpful authority. (80)

Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" (81)

We reveal the Quran which is a cure and mercy for the believers but does nothing for the unjust except to lead them to perdition. (82)

When We do favors to the human being, he disregards it and turns away from it. When evil afflicts him, he becomes despairing. (83)

Say, "Everyone does as he wants. Your Lord knows best who has the right guidance." (84)
