The word(s) "edge" appears 131 time(s) in 125 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) They ask you about the hour, when will be its taking place? Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but most people do not know.

(32) Is he, therefore, better who lays his foundation on fear of Allah and (His) good pleasure, or he who lays his foundation on the edge of a cracking hollowed bank, so it broke down with him into the fire of hell; and Allah does not guide the unjust people.

(33) Surely Allah has bought of the believers their persons and their property for this, that they shall have the garden; they fight in Allah's way, so they slay and are slain; a promise which is binding on Him in the Taurat and the Injeel and the Quran; and who is more faithful to his covenant than Allah? Rejoice therefore in the pledge which you have made; and that is the mighty achievement.

(34) Nay, they reject that of which they have no comprehensive knowledge, and the final sequel of it has not yet come to them; even thus did those before them reject (the truth); see then what was the end of the unjust.

(35) And certainly We lodged the children of Israel in a goodly abode and We provided them with good things; but they did not disagree until the knowledge had come to them; surely your Lord will judge between them on the resurrection day concerning that in which they disagreed.

(36) But if they do not answer you, then know that it is revealed by Allah's knowledge and that there is no god but He; will you then submit?

(37) He said: O Nuh! surely he is not of your family; surely he is (the doer of) other than good deeds, therefore ask not of Me that of which you have no knowledge; surely I admonish you lest you may be of the ignorant

(38) He said: My Lord! I seek refuge in Thee from asking Thee that of which I have no knowledge; and if Thou shouldst not forgive me and have mercy on me, I should be of the losers.

(39) And when he had attained his maturity, We gave him wisdom and knowledge: and thus do We reward those who do good.

(40) And when they had entered as their father had bidden them, it did not avail them aught against Allah, but (it was only) a desire in the soul of Yaqoub which he satisfied; and surely he was possessed of knowledge because We had given him knowledge, but most people do not know.
