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

(141) And among them are some who listen to you (O Muhammad صلى الله عليه وسلم) till when they go out from you, they say to those who have received knowledge: "What has he said just now? Such are men whose hearts Allah has sealed, and they follow their lusts (evil desires).

(142) Verily, those who give Bai'ah (pledge) to you (O Muhammad صلى الله عليه وسلم) they are giving Bai'ah (pledge) to Allah. The Hand of Allah is over their hands. Then whosoever breaks his pledge, breaks it only to his own harm; and whosoever fulfils what he has covenanted with Allah, He will bestow on him a great reward.

(143) Indeed, Allah was pleased with the believers when they gave the Bai'ah (pledge) to you (O Muhammad صلى الله عليه وسلم) under the tree: He knew what was in their hearts, and He sent down As-Sakinah (calmness and tranquillity) upon them, and He rewarded them with a near victory.

(144) They are the ones who disbelieved (in the Oneness of Allah - Islamic Monotheism) and hindered you from Al-Masjid-al-Haram (at Makkah) and detained the sacrificial animals from reaching their place of sacrifice. Had there not been believing men and believing women whom you did not know, that you may kill them and on whose account a sin would have been committed by you without (your) knowledge, that Allah might bring into His Mercy whom He wills - if they (the believers and the disbelievers) had been apart, We verily would have punished those of them who disbelieved with painful torment.

(145) And indeed We have created man, and We know what his ownself whispers to him. And We are nearer to him than his jugular vein (by Our Knowledge).

(146) Then he conceived fear of them (when they ate not). They said: "Fear not." And they gave him glad tidings of a son having knowledge (about Allah and His religion of True Monotheism).

(147) And those who believe and whose offspring follow them in Faith: to them shall We join their offspring, and We shall not decrease the reward of their deeds in anything. Every person is a pledge for that which he has earned.

(148) But they have no knowledge thereof. They follow but a guess, and verily, guess is no substitute for the truth.

(149) That is what they could reach of knowledge. Verily, your Lord it is He Who knows best him who goes astray from His Path, and He knows best him who receives guidance.

(150) Is with him the knowledge of the Unseen so that he sees?
