The word(s) "acquainted" appears 52 time(s) in 52 verse(s) in Quran in Abdullah Yusuf Ali translation.

(31) Seest thou not that Allah merges Night into Day and he merges Day into Night; that He has subjected the sun, and the moon (to his Law), each running its course for a term appointed; and that Allah is well-acquainted with all that ye do?

(32) Verily the knowledge of the Hour is with Allah (alone). It is He Who sends down rain, and He Who knows what is in the wombs. Nor does any one know what it is that he will earn on the morrow: Nor does any one know in what land he is to die. Verily with Allah is full knowledge and He is acquainted (with all things).

(33) But follow that which comes to thee by inspiration from thy Lord: for Allah is well acquainted with (all) that ye do.

(34) And recite what is rehearsed to you in your homes, of the Signs of Allah and His Wisdom: for Allah understands the finest mysteries and is well-acquainted (with them).

(35) Praise be to Allah, to Whom belong all things in the heavens and on earth: to Him be Praise in the Hereafter: and He is Full of Wisdom, acquainted with all things.

(36) If ye invoke them, they will not listen to your call, and if they were to listen, they cannot answer your (prayer). On the Day of Judgment they will reject your "Partnership". and none, (O man!) can tell thee (the Truth) like the One Who is acquainted with all things.

(37) That which We have revealed to thee of the Book is the Truth,- confirming what was (revealed) before it: for Allah is assuredly- with respect to His Servants - well acquainted and Fully Observant.

(38) If Allah were to enlarge the provision for His Servants, they would indeed transgress beyond all bounds through the earth; but he sends (it) down in due measure as He pleases. For He is with His Servants Well-acquainted, Watchful.

(39) The desert Arabs who lagged behind will say to thee: "We were engaged in (looking after) our flocks and herds, and our families: do thou then ask forgiveness for us." They say with their tongues what is not in their hearts. Say: "Who then has any power at all (to intervene) on your behalf with Allah, if His Will is to give you some loss or to give you some profit? But Allah is well acquainted with all that ye do.

(40) O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). Verily the most honoured of you in the sight of Allah is (he who is) the most righteous of you. And Allah has full knowledge and is well acquainted (with all things).
