The word(s) "edge" appears 175 time(s) in 163 verse(s) in Quran in Mohsin Khan translation.

(91) And among mankind is he who disputes concerning Allah, without knowledge, and follows every rebellious (disobedient to Allah) Shaitan (devil) (devoid of every kind of good).

(92) And among men is he who disputes about Allah, without knowledge or guidance, or a Book giving light (from Allah),

(93) And among mankind is he who worships Allah as it were, upon the edge (i.e. in doubt): if good befalls him, he is content therewith; but if a trial befalls him, he turns back on his face (i.e. reverts to disbelief after embracing Islam).

(98) "So I fled from you when I feared you. But my Lord has granted me Hukm (i.e. religious knowledge, right judgement of the affairs and Prophethood), and made me one of the Messengers.

(99) My Lord! Bestow Hukm (religious knowledge, right judgement of the affairs and Prophethood) on me, and join me with the righteous.

(100) He said: "And what knowledge have I of what they used to do?
