The word(s) "all-knowing" appears 21 time(s) in 21 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) The Arabs of the desert are the worst in Unbelief and hypocrisy, and most fitted to be in ignorance of the command which Allah hath sent down to His Messenger: But Allah is all-knowing, All-Wise.

(12) There are (yet) others, held in suspense for the command of Allah, whether He will punish them, or turn in mercy to them: and Allah is all-knowing, Wise.

(13) The foundation of those who so build is never free from suspicion and shakiness in their hearts, until their hearts are cut to pieces. And Allah is all-knowing, Wise.

(14) So he began (the search) with their baggage, before (he came to) the baggage of his brother: at length he brought it out of his brother's baggage. Thus did We plan for Joseph. He could not take his brother by the law of the king except that Allah willed it (so). We raise to degrees (of wisdom) whom We please: but over all endued with knowledge is one, the all-knowing.

(15) It is Allah who creates you and takes your souls at death; and of you there are some who are sent back to a feeble age, so that they know nothing after having known (much): for Allah is all-knowing, All-Powerful.

(16) Verily He will admit them to a place with which they shall be well pleased: for Allah is all-knowing, Most Forbearing.

(18) Verily thy Lord will decide between them by His Decree: and He is Exalted in Might, all-knowing.

(19) Thou mayest defer (the turn of) any of them that thou pleasest, and thou mayest receive any thou pleasest: and there is no blame on thee if thou invite one whose (turn) thou hadst set aside. This were nigher to the cooling of their eyes, the prevention of their grief, and their satisfaction - that of all of them - with that which thou hast to give them: and Allah knows (all) that is in your hearts: and Allah is all-knowing, Most Forbearing.

(20) Do they not travel through the earth, and see what was the End of those before them,- though they were superior to them in strength? Nor is Allah to be frustrated by anything whatever in the heavens or on earth: for He is all-knowing. All-Powerful.
