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

(71) And (He has created) horses, mules and donkeys, for you to ride and as an adornment. And He creates (other) things of which you have no knowledge.

(72) They may bear their own burdens in full on the Day of Resurrection, and also of the burdens of those whom they misled without knowledge. Evil indeed is that which they shall bear!

(73) Then, on the Day of Resurrection, He will disgrace them and will say: "Where are My (so called) partners concerning whom you used to disagree and dispute (with the believers, by defying and disobeying Allah)?" Those who have been given the knowledge (about the Torment of Allah for the disbelievers) will say: "Verily! Disgrace and misery this Day are upon the disbelievers.

(74) And fulfil the Covenant of Allah (Bai'ah: pledge for Islam) when you have covenanted, and break not the oaths after you have confirmed them - and indeed you have appointed Allah your surety. Verily! Allah knows what you do.

(75) And follow not (O man i.e., say not, or do not or witness not) that of which you have no knowledge. Verily! The hearing, and the sight, and the heart, of each of those one will be questioned (by Allah).

(76) And they ask you (O Muhammad صلى الله عليه و سلم) concerning the Ruh (the Spirit); Say: "The Ruh (the Spirit) is one of the things, the knowledge of which is only with my Lord. And of knowledge, you (mankind) have been given only a little."

(77) Say (O Muhammad صلى الله عليه و سلم to them): "Believe in it (the Qur'an) or do not believe (in it). Verily those who were given knowledge before it (the Jews and the Christians like 'Abdullah bin Salam and Salman Al-Farisi), when it is recited to them, fall down on their faces in humble prostration."

(78) No knowledge have they of such a thing, nor had their fathers. Mighty is the word that comes out of their mouths [i.e. He begot sons and daughters]. They utter nothing but a lie .

(79) Say: "Allah knows best how long they stayed. With Him is (the knowledge of) the Unseen of the heavens and the earth. How clearly He sees, and hears (everything)! They have no Wali (Helper, Disposer of affairs, Protector) other than Him, and He makes none to share in His Decision and His Rule."

(80) Then they found one of Our slaves, on whom We had bestowed mercy from Us, and whom We had taught knowledge from Us.
