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

(31) It is He Who has set the stars for you, so that you may guide your course with their help through the darkness of the land and the sea. We have (indeed) explained in detail Our Ayat (proofs, evidence, verses, lessons, signs, Revelations, etc.) for people who know.

(32) So eat of that (meat) on which Allah's Name has been pronounced (while slaughtering the animal), if you are believers in His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(33) Say: "Bring forward your witnesses, who can testify that Allah has forbidden this. Then if they testify, testify not you (O Muhammad صلى الله عليه وسلم) with them. And you should not follow the vain desires of such as treat Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) as falsehoods, and such as believe not in the Hereafter, and they hold others as equal (in worship) with their Lord."

(34) Or lest you (pagan Arabs) should say: "If only the Book had been sent down to us, we would surely have been better guided than they (Jews and Christians)." So now has come unto you a clear proof (the Qur'an) from your Lord, and a guidance and a mercy. Who then does more wrong than one who rejects the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah and turns away therefrom? We shall requite those who turn away from Our Ayat with an evil torment, because of their turning away (from them). [Tafsir At-Tabari]

(35) And as for those whose scale will be light, they are those who will lose their ownselves (by entering Hell) because they denied and rejected Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(36) O Children of Adam! We have bestowed raiment upon you to cover yourselves (screen your private parts) and as an adornment; and the raiment of righteousness, that is better. Such are among the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, that they may remember (i.e. leave falsehood and follow truth ).

(37) But those who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations) and treat them with arrogance, they are the dwellers of the (Hell) Fire, they will abide therein forever.

(38) Who is more unjust than one who invents a lie against Allah or rejects His Ayat (proofs, evidence, verses, lessons, signs, revelations)? For such their appointed portion (good things of this worldly life and their period of stay therein) will reach them from the Book (of Decrees) until when Our Messengers (the angel of death and his assistants) come to them to take their souls, they (the angels) will say: "Where are those whom you used to invoke and worship besides Allah," they will reply, "They have vanished and deserted us." And they will bear witness against themselves, that they were disbelievers.

(39) Verily, those who belie Our Ayat (proofs, evidence, verses, lessons, signs, revelations) and treat them with arrogance, for them the gates of heaven will not be opened, and they will not enter Paradise until the camel goes through the eye of the needle (which is impossible). Thus do We recompense the Mujrimun (criminals, polytheists and sinners).

(40) "Who took their religion as an amusement and play, and the life of the world deceived them." So this Day We shall forget them as they forgot their meeting of this Day, and as they used to reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations).
