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

(131) To Him (Alone) is referred the knowledge of the Hour. No fruit comes out of its sheath, nor does a female conceive nor brings forth (young), except by His Knowledge. And on the Day when He will call unto them (polytheists) (saying): "Where are My (so-called) partners (whom you did invent)?" They will say: "We inform You that none of us bears witness to it (that they are Your partners)!"

(132) And they divided not till after knowledge had come to them, through (selfish) transgression between themselves. And had it not been for a Word that went forth before from your Lord for an appointed term, the matter would have been settled between them. And verily, those who were made to inherit the Scripture [i.e. the Taurah (Torah) and the Injeel (Gospel)] after them (i.e. Jews and Christians) are in grave doubt concerning it (i.e. Allah's true religion - Islam or the Qur'an).

(133) And they said: "If it had been the Will of the Most Gracious (Allah), we should not have worshipped them (false deities)." They have no knowledge whatsoever of that. They do nothing but lie!

(134) And Blessed be He to Whom belongs the kingdom of the heavens and the earth, and all that is between them, and with Whom is the knowledge of the Hour, and to Whom you (all) will be returned.

(135) (And Allah has the knowledge) of (Prophet Muhammad's) saying: "O my Lord! Verily, these are a people who believe not!"

(136) And We chose them (the Children of Israel) above the 'Alamin (mankind and jinn) [during the time of Musa (Moses)] with knowledge,

(137) And gave them clear proofs in matters [by revealing to them the Taurat (Torah)]. And they differed not until after the knowledge came to them, through envy among themselves. Verily, Your Lord will judge between them on the Day of Resurrection about that wherein they used to differ.

(138) And they say: "There is nothing but our life of this world, we die and we live and nothing destroys us except Ad-Dahr (time). And they have no knowledge of it: they only conjecture.

(139) Say (O Muhammad صلى الله عليه وسلم to these pagans): "Think you about all that you invoke besides Allah? Show me. What have they created of the earth? Or have they a share in (the creation of) the heavens? Bring me a Book (revealed before this), or some trace of knowledge (in support of your claims), if you are truthful!"

(140) He said: "The knowledge (of the time of its coming) is with Allah only. And I convey to you that wherewith I have been sent, but I see that you are a people given to ignorance!"
