The word(s) "understand" appears 98 time(s) in 98 verse(s) in Quran in Mohsin Khan translation.

(81) It is He, Who has created you (Adam) from dust, then from a Nutfah [mixed semen drops of male and female sexual discharge (i.e. Adam's offspring)] then from a clot (a piece of coagulated blood), then brings you forth as an infant, then (makes you grow) to reach the age of full strength, and afterwards to be old (men and women)- though some among you die before,- and that you reach an appointed term in order that you may understand.

(82) And if We had sent this as a Qur'an in a foreign language (other than Arabic), they would have said: "Why are not its verses explained in detail (in our language)? What! (A Book) not in Arabic and (the Messenger) an Arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur'an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."

(83) Verily, We have made it a Qur'an in Arabic that you may be able to understand (its meanings and its admonitions).

(84) And in the alternation of night and day, and the provision (rain) that Allah sends down from the sky, and revives therewith the earth after its death, and in the turning about of the winds (i.e. sometimes towards the east or north, and sometimes towards the south or west sometimes bringing glad tidings of rain etc., and sometimes bringing the torment), are signs for a people who understand.

(85) And indeed We gave the Children of Israel the Scripture, and the understanding of the Scripture and its laws, and the Prophethood; and provided them with good things, and preferred them above the 'Alamin (mankind and jinn of their time, during that period),

(86) Do they not then think deeply in the Qur'an, or are their hearts locked up (from understanding it)?

(87) Those who lagged behind will say, when you set forth to take the spoils, "Allow us to follow you." They want to change Allah's Words. Say: "You shall not follow us; thus Allah has said beforehand." Then they will say: "Nay, you envy us." Nay, but they understand not except a little.

(88) And We have indeed made the Qur'an easy to understand and remember; then is there any one who will remember (or receive admonition)?

(89) And We have indeed made the Qur'an easy to understand and remember; then is there any that will remember (or receive admonition)?

(90) And indeed, We have made the Qur'an easy to understand and remember; then is there any that will remember (or receive admonition)?
