The word(s) "knows" appears 161 time(s) in 141 verse(s) in Quran in Mohsin Khan translation.

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

(2) Know they (Jews) not that Allah knows what they conceal and what they reveal?

(3) Or say you that Ibrahim (Abraham), Isma'il (Ishmael), Ishaq (Isaac), Ya'qub (Jacob) and Al-Asbat [the offspring of the twelve sons of Ya'qub (Jacob)] were Jews or Christians? Say, "Do you know better or does Allah (knows better ... that they all were Muslims)? And who is more unjust than he who conceals the testimony [i.e. to believe in Prophet Muhammad صلى الله عليه وسلم when he comes, as is written in their Books. (See Verse 7:157)] he has from Allah? And Allah is not unaware of what you do."

(4) It is made lawful for you to have sexual relations with your wives on the night of As-Saum (the fasts). They are Libas [i.e. body cover, or screen, or Sakan, (i.e. you enjoy the pleasure of living with them - as in Verse 7:189) Tafsir At-Tabari ], for you and you are the same for them. Allah knows that you used to deceive yourselves, so He turned to you (accepted your repentance) and forgave you. So now have sexual relations with them and seek that which Allah has ordained for you (offspring), and eat and drink until the white thread (light) of dawn appears to you distinct from the black thread (darkness of night), then complete your Saum (fast) till the nightfall. And do not have sexual relations with them (your wives) while you are in I'tikaf (i.e. confining oneself in a mosque for prayers and invocations leaving the worldly activities) in the mosques. These are the limits (set) by Allah, so approach them not. Thus does Allah make clear His Ayat (proofs, evidence, lessons, signs, revelations, verses, laws, legal and illegal things, Allah's set limits, orders) to mankind that they may become Al-Muttaqun (the pious - See V.2:2).

(5) The Hajj (pilgrimage) is (in) the well-known (lunar year) months (i.e. the 10th month, the 11th month and the first ten days of the 12th month of the Islamic calendar, i.e. two months and ten days). So whosoever intends to perform Hajj therein (by assuming Ihram), then he should not have sexual relations (with his wife), nor commit sin, nor dispute unjustly during the Hajj. And whatever good you do, (be sure) Allah knows it. And take a provision (with you) for the journey, but the best provision is At-Taqwa (piety, righteousness). So fear Me, O men of understanding!

(6) They ask you (O Muhammad صلى الله عليه وسلم) what they should spend. Say: Whatever you spend of good must be for parents and kindred and orphans and Al-Masakin (the poor) and the wayfarer, and whatever you do of good deeds, truly, Allah knows it well.

(7) Jihad (holy fighting in Allah's cause) is ordained for you (Muslims) though you dislike it, and it may be that you dislike a thing which is good for you and that you like a thing which is bad for you. Allah knows but you do not know.

(8) In (to) this worldly life and in the Hereafter. And they ask you concerning orphans. Say: "The best thing is to work honestly in their property, and if you mix your affairs with theirs, then they are your brothers. And Allah knows him who means mischief (e.g. to swallow their property) from him who means good (e.g. to save their property). And if Allah had wished, He could have put you into difficulties. Truly, Allah is All-Mighty, All-Wise."

(9) And when you have divorced women and they have fulfilled the term of their prescribed period, do not prevent them from marrying their (former) husbands, if they mutually agree on reasonable basis. This (instruction) is an admonition for him among you who believes in Allah and the Last Day. That is more virtuous and purer for you. Allah knows and you know not.

(10) And there is no sin on you if you make a hint of betrothal or conceal it in yourself, Allah knows that you will remember them, but do not make a promise of contract with them in secret except that you speak an honourable saying according to the Islamic law. And do not consummate the marriage until the term prescribed is fulfilled. And know that Allah knows what is in your minds, so fear Him. And know that Allah is Oft-Forgiving, Most Forbearing.
