The word(s) "understanding" appears 33 time(s) in 33 verse(s) in Quran in Mohsin Khan translation.

(11) Say (O Muhammad صلى الله عليه وسلم): "Not equal are Al-Khabith (all that is evil and bad as regards things, deeds, beliefs, persons and foods) and At-Taiyyib (all that is good as regards things, deeds, beliefs, persons, foods), even though the abundance of Al-Khabith may please you." So fear Allah , O men of understanding in order that you may be successful.

(12) Allah has not instituted things like Bahirah , or Sa'ibah , or Wasilah , or Ham , (all these animals were liberated in honour of idols as practised by pagan Arabs in the pre-Islamic period). But those who disbelieve invent lies against Allah, and most of them have no understanding.

(13) (Remember) when Allah will say (on the Day of Resurrection). "O 'Îsa (Jesus), son of Maryam (Mary)! Remember My Favour to you and to your mother when I supported you with Ruh-ul-Qudus [Jibril (Gabriel)] so that you spoke to the people in the cradle and in maturity; and when I taught you writing, Al-Hikmah (the power of understanding), the Taurat (Torah) and the Injeel (Gospel); and when you made out of the clay a figure like that of a bird, by My Permission, and you breathed into it, and it became a bird by My Permission, and you healed those born blind, and the lepers by My Permission, and when you brought forth the dead by My Permission; and when I restrained the Children of Israel from you (when they resolved to kill you) as you came unto them with clear proofs, and the disbelievers among them said: 'This is nothing but evident magic.'"

(14) They are those whom We gave the Book, Al-Hukm (understanding of the religious laws), and Prophethood. But if these disbelieve therein (the Book, Al-Hukm and Prophethood), then, indeed We have entrusted it to a people (such as the Companions of Prophet Muhammad صلى الله عليه وسلم) who are not disbelievers therein.

(15) Indeed in their stories, there is a lesson for men of understanding. It (the Qur'an) is not a forged statement but a confirmation of (Allah's existing Books) which were before it [i.e. the Taurat (Torah), the Injeel (Gospel) and other Scriptures of Allah] and a detailed explanation of everything and a guide and a Mercy for the people who believe.

(16) Shall he then who knows that what has been revealed unto you (O Muhammad صلى الله عليه و سلم) from your Lord is the truth be like him who is blind? But it is only the men of understanding that pay heed.

(17) This (Qur'an) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One Ilah (God - Allah) - (none has the right to be worshipped but Allah) - and that men of understanding may take heed.

(18) Eat and pasture your cattle (therein); verily, in this are Ayat (proofs and signs) for men of understanding.

(19) Is it not a guidance for them (to know) how many generations We have destroyed before them, in whose dwellings they walk? Verily, in this are signs indeed for men of understanding.

(20) Nay, but their hearts are covered from (understanding) this (the Qur'an), and they have other (evil) deeds, besides, which they are doing.
