The word(s) "explain" appears 36 time(s) in 35 verse(s) in Quran in Mohsin Khan translation.

(31) A Book whereof the Verses are explained in detail - a Qur'an in Arabic for people who know.

(32) 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)."

(33) How can there be for them an admonition (at the time when the torment has reached them), when a Messenger explaining things clearly has already come to them.

(34) Those who believe say: "Why is not a Surah (chapter of the Qur'an) sent down (for us)? But when a decisive Surah (explaining and ordering things) is sent down, and fighting (Jihad - holy fighting in Allah's cause) is mentioned (i.e. ordained) therein, you will see those in whose hearts is a disease (of hypocrisy) looking at you with a look of one fainting to death. But it was better for them (hypocrites, to listen to Allah and to obey Him).

(35) And what will explain to you what is the Day of Sorting Out?
