5 verses have
edge
in Edition Clear Qur'an by Talal Itani / Al-Hajj (The Pilgrimage)

22:3Among the people is he who argues about God without knowledge, and follows every defiant devil.

22:8And among the people is he who argues about God without knowledge, or guidance, or an enlightening scripture.

22:11And among the people is he who worships God on edge. When something good comes his way, he is content with it. But when an ordeal strikes him, he makes a turnaround. He loses this world and the next. That is the obvious loss.

22:54And so that those endowed with knowledge may know that it is the truth from your Lord, and so believe in it, and their hearts soften to it. God guides those who believe to a straight path.

22:71Yet they worship, besides God, things for which He sent down no warrant, and what they have no knowledge of. There is no savior for the transgressors.
