The word(s) "lessons" appears 150 time(s) in 149 verse(s) in Quran in Mohsin Khan translation.

(101) And for each (of them) We put forward examples (as proofs and lessons), and each (of them) We brought to utter ruin (because of their disbelief and evil deeds).

(102) And those who, when they are reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord, fall not deaf and blind thereat.

(103) But when Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) came to them, clear to see, they said: "This is a manifest magic."

(104) Nor can you lead the blind out of their error. You can only make to hear those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and who have submitted (themselves to Allah in Islam as Muslims).

(105) And (remember) the Day when We shall gather out of every nation a troop of those who denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and (then) they (all) shall be driven (to the place of reckoning),

(106) Till, when they come (before their Lord at the place of reckoning), He will say: "Did you deny My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) whereas you comprehended them not by knowledge (of their truth or falsehood), or what (else) was it that you used to do?"

(107) See they not that We have made the night for them to rest therein, and the day sight-giving? Verily, in this are Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) for the people who believe.

(108) Allah said: "We will strengthen your arm through your brother, and give you both power, so they shall not be able to harm you: with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), you two as well as those who follow you will be the victors."

(109) Then when Musa (Moses) came to them with Our Clear Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they said: "This is nothing but invented magic. Never did we hear of this among our fathers of old."

(110) And those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah and the Meeting with Him, it is they who have no hope of My Mercy: and it is they who will have a painful torment.
