The word(s) "understand" appears 127 time(s) in 127 verse(s) in Quran in Abdullah Yusuf Ali translation.

(71) Thus did We restore him to his mother, that her eye might be comforted, that she might not grieve, and that she might know that the promise of Allah is true: but most of them do not understand.

(72) They say: "If we were to follow the guidance with thee, we should be snatched away from our land." Have We not established for them a secure sanctuary, to which are brought as tribute fruits of all kinds,- a provision from Ourselves? but most of them understand not.

(73) And (We also saved) Abraham: behold, he said to his people, "Serve Allah and fear Him: that will be best for you- If ye understand!

(74) And We have left thereof an evident Sign, for any people who (care to) understand.

(75) And such are the Parables We set forth for mankind, but only those understand them who have knowledge.

(76) And if indeed thou ask them who it is that sends down rain from the sky, and gives life therewith to the earth after its death, they will certainly reply, "Allah!" Say, "Praise be to Allah!" But most of them understand not.

(77) (It is) the promise of Allah. Never does Allah depart from His promise: but most men understand not.

(78) He does propound to you a similitude from your own (experience): do ye have partners among those whom your right hands possess, to share as equals in the wealth We have bestowed on you? Do ye fear them as ye fear each other? Thus do we explain the Signs in detail to a people that understand.

(79) So set thou thy face steadily and truly to the Faith: (establish) Allah's handiwork according to the pattern on which He has made mankind: no change (let there be) in the work (wrought) by Allah: that is the standard Religion: but most among mankind understand not.

(80) Thus does Allah seal up the hearts of those who understand not.
