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

(571) Say (to them): "Allah gives you life, then causes you to die, then He will assemble you on the Day of Resurrection about which there is no doubt. But most of mankind know not."

(572) And when it was said: "Verily, Allah's Promise is the truth, and there is no doubt about the coming of the Hour," you said: "We know not what is the Hour: we do not think it but as a conjecture, and we have no firm convincing belief (therein)."

(573) Ha-Mim. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings].

(574) 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!"

(575) Or say they: "He (Muhammad صلى الله عليه وسلم) has fabricated it." Say: "If I have fabricated it? still you have no power to support me against Allah. He knows best of what you say among yourselves concerning it (i.e. this Qur'an)! Sufficient is He as a witness between me and you! And He is the Oft-Forgiving, the Most Merciful."

(576) Say (O Muhammad صلى الله عليه وسلم): "I am not a new thing among the Messengers (of Allah i.e. I am not the first Messenger) nor do I know what will be done with me or with you. I only follow that which is revealed to me, and I am but a plain warner."

(577) 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!"

(578) And admit them to Paradise which He has made known to them (i.e. they will know their places in Paradise better than they used to know their homes in the world). [Tafsir Ibn Kathir ]

(579) 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).

(580) So know (O Muhammad صلى الله عليه وسلم) that, La ilaha illallah (none has the right to be worshipped but Allah) , and ask forgiveness for your sin, and also for (the sin of) believing men and believing women. And Allah knows well your moving about, and your place of rest (in your homes).
