The word(s) "know" appears 814 time(s) in 684 verse(s) in Quran in Mohsin Khan translation.

(541) Then He completed and finished from their creation (as) seven heavens in two Days and He made in each heaven its affair. And We adorned the nearest (lowest) heaven with lamps (stars) to be an adornment as well as to guard (from the devils by using them as missiles against the devils). Such is the Decree of Him the All-Mighty, the All-knower.

(542) And if an evil whisper from Shaitan (Satan) tries to turn you away (O Muhammad صلى الله عليه وسلم) (from doing good), then seek refuge in Allah. Verily, He is the All-Hearer, the All-knower.

(543) 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)!"

(544) 'Ain-Sin-Qaf. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings].

(545) To Him belong the keys of the heavens and the earth. He enlarges provision for whom He wills, and straitens (it for whom He wills). Verily He is the All-knower of everything.

(546) 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).

(547) It is Allah Who has sent down the Book (the Qur'an) in truth, and the Balance (i.e. to act justly). And what can make you know that perhaps the Hour is close at hand?

(548) Those who believe not therein seek to hasten it, while those who believe are fearful of it, and know that it is the very truth. Verily, those who dispute concerning the Hour are certainly in error far away.

(549) Or say they: "He has invented a lie against Allah?" If Allah willed, He could have sealed up your heart (so that you forget all that you know of the Qur'an). And Allah wipes out falsehood, and establishes the truth (Islam) by His Word (this Qur'an). Verily, He knows well what (secrets) are in the breasts (of mankind).

(550) And He it is Who accepts repentance from His slaves, and forgives sins, and He knows what you do.
