The word(s) "know" appears 656 time(s) in 561 verse(s) in Quran in Abdullah Yusuf Ali translation.

(171) "Because Allah will never change the grace which He hath bestowed on a people until they change what is in their (own) souls: and verily Allah is He Who heareth and knoweth (all things)."

(172) Against them make ready your strength to the utmost of your power, including steeds of war, to strike terror into (the hearts of) the enemies, of Allah and your enemies, and others besides, whom ye may not know, but whom Allah doth know. Whatever ye shall spend in the cause of Allah, shall be repaid unto you, and ye shall not be treated unjustly.

(173) But if the enemy incline towards peace, do thou (also) incline towards peace, and trust in Allah: for He is One that heareth and knoweth (all things).

(174) For the present, Allah hath lightened your (task), for He knoweth that there is a weak spot in you: But (even so), if there are a hundred of you, patient and persevering, they will vanquish two hundred, and if a thousand, they will vanquish two thousand, with the leave of Allah: for Allah is with those who patiently persevere.

(175) But if they have treacherous designs against thee, (O Messenger!), they have already been in treason against Allah, and so hath He given (thee) power over them. And Allah so He Who hath (full) knowledge and wisdom.

(176) Go ye, then, for four months, backwards and forwards, (as ye will), throughout the land, but know ye that ye cannot frustrate Allah (by your falsehood) but that Allah will cover with shame those who reject Him.

(177) And an announcement from Allah and His Messenger, to the people (assembled) on the day of the Great Pilgrimage,- that Allah and His Messenger dissolve (treaty) obligations with the Pagans. If then, ye repent, it were best for you; but if ye turn away, know ye that ye cannot frustrate Allah. And proclaim a grievous penalty to those who reject Faith.

(178) If one amongst the Pagans ask thee for asylum, grant it to him, so that he may hear the word of Allah; and then escort him to where he can be secure. That is because they are men without knowledge.

(179) And still the indignation of their hearts. For Allah will turn (in mercy) to whom He will; and Allah is All-knowing, All-Wise.

(180) Or think ye that ye shall be abandoned, as though Allah did not know those among you who strive with might and main, and take none for friends and protectors except Allah, His Messenger, and the (community of) Believers? But Allah is well-acquainted with (all) that ye do.
