The word(s) "well-acquainted" appears 19 time(s) in 19 verse(s) in Quran in Mohsin Khan translation.

(11) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an and none but Allah (Alone) knows their meanings]. (This is) a Book, the Verses whereof are perfected (in every sphere of knowledge), and then explained in detail from One (Allah) Who is All-Wise well-acquainted (with all things).

(12) And indeed We bestowed aforetime on Ibrahim (Abraham) his (portion of) guidance, and We were well-acquainted with him (as to his Belief in the Oneness of Allah).

(13) See you not that Allah sends down water (rain) from the sky, and then the earth becomes green? Verily, Allah is the Most Kind and Courteous, well-acquainted with all things.

(14) O (you) Messengers! Eat of the Tayyibat [all kinds of Halal foods which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables, fruits, etc.] and do righteous deeds. Verily! I am well-acquainted with what you do.

(15) And you will see the mountains and think them solid, but they shall pass away as the passing away of the clouds. The Work of Allah, Who perfected all things, verily He is well-acquainted with what you do.

(16) And follow that which is revealed to you from your Lord. Verily, Allah is well-acquainted with what you do.

(17) And remember (O you the members of the Prophet's family, the Graces of your Lord), that which is recited in your houses of the Verses of Allah and Al-Hikmah (i.e. Prophet's Sunnah - legal ways, so give your thanks to Allah and glorify His Praises for this Qur'an and the Sunnah ). Verily, Allah is Ever Most Courteous, well-acquainted with all things.

(18) O you who believe! When you are told to make room in the assemblies, (spread out and) make room. Allah will give you (ample) room (from His Mercy). And when you are told to rise up [for prayers, or Jihad (holy fighting in Allah's cause), or for any other good deed], rise up. Allah will exalt in degree those of you who believe, and those who have been granted knowledge. And Allah is well-acquainted with what you do.

(19) Verily, that Day (i.e. the Day of Resurrection) their Lord will be well-acquainted with them (as to their deeds and will reward them for their deeds).
