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

(51) And Allah knows what you conceal and what you reveal.

(52) Certainly, Allah knows what they conceal and what they reveal. Truly, He likes not the proud.

(53) So put not forward similitudes for Allah (as there is nothing similar to Him, nor He resembles anything). Truly! Allah knows and you know not.

(54) And fulfil the Covenant of Allah (Bai'ah: pledge for Islam) when you have covenanted, and break not the oaths after you have confirmed them - and indeed you have appointed Allah your surety. Verily! Allah knows what you do.

(55) And when We change a Verse (of the Qur'an,) in place of another - and Allah knows best what He sends down - they (the disbelievers) say: "You (O Muhammad صلى الله عليه و سلم) are but a Muftari! (forger, liar)." Nay, but most of them know not.

(56) Invite (mankind, O Muhammad صلى الله عليه و سلم) to the Way of your Lord (i.e. Islam) with wisdom (i.e. with the Divine Revelation and the Qur'an) and fair preaching, and argue with them in a way that is better. Truly, your Lord knows best who has gone astray from His Path, and He is the Best Aware of those who are guided.

(57) Your Lord knows best what is in your inner-selves. If you are righteous, then, verily, He is Ever Most Forgiving to those who turn unto Him again and again in obedience, and in repentance.

(58) Your Lord knows you best; if He wills, He will have mercy on you, or if He wills, He will punish you. And We have not sent you (O Muhammad صلى الله عليه و سلم) as a guardian over them.

(59) And your Lord knows best all who are in the heavens and the earth. And indeed, We have preferred some of the Prophets above others, and to Dawud (David) We gave the Zabur (Psalms).

(60) Say (O Muhammad صلى الله عليه و سلم to mankind): "Each one does according to Shakilatihi (i.e. his way or his religion or his intentions.), and your Lord knows best of him whose path (religion) is right."
