The word(s) "plain" appears 101 time(s) in 98 verse(s) in Quran in Mohsin Khan translation.

(1) And (remember) when you said: "O Musa (Moses)! We shall never believe in you until we see Allah plainly." But you were seized with a thunder-bolt (lightning) while you were looking.

(2) They said, "Call upon your Lord for us that He may make plain to us what it is!" He said, "He says, 'Verily, it is a cow neither too old nor too young, but (it is) between the two conditions', so do what you are commanded."

(3) They said, "Call upon your Lord for us to make plain to us its colour." He said, "He says, 'It is a yellow cow, bright in its colour, pleasing to the beholders.' "

(4) They said, "Call upon your Lord for us to make plain to us what it is. Verily, to us all cows are alike. And surely, if Allah wills, we will be guided."

(5) And those who have no knowledge say: "Why does not Allah speak to us (face to face) or why does not a sign come to us?" So said the people before them words of similar import. Their hearts are alike, We have indeed made plain the signs for people who believe with certainty.

(6) O you who believe! Enter perfectly in Islam (by obeying all the rules and regulations of the Islamic religion) and follow not the footsteps of Shaitan (Satan). Verily! He is to you a plain enemy.

(7) And if he has divorced her (the third time), then she is not lawful unto him thereafter until she has married another husband. Then, if the other husband divorces her, it is no sin on both of them that they reunite, provided they feel that they can keep the limits ordained by Allah. These are the limits of Allah, which He makes plain for the people who have knowledge.

(8) O you who believe! Take not as (your) Bitanah (advisors, consultants, protectors, helpers, friends) those outside your religion (pagans, Jews, Christians, and hypocrites) since they will not fail to do their best to corrupt you. They desire to harm you severely. Hatred has already appeared from their mouths, but what their breasts conceal is far worse. Indeed We have made plain to you the Ayat (proofs, evidence, verses) if you understand.

(9) This (the Qur'an) is a plain statement for mankind, a guidance and instruction to those who are Al-Muttaqun (the pious - See V.2:2).

(10) O people of the Scripture (Jews and Christians)! Now has come to you Our Messenger (Muhammad صلى الله عليه وسلم) explaining to you much of that which you used to hide from the Scripture and pass over (i.e. leaving out without explaining) much. Indeed, there has come to you from Allah a light (Prophet Muhammad صلى الله عليه وسلم) and a plain Book (this Qur'an).
