The word(s) "lesson" appears 6 time(s) in 6 verse(s) in Quran in Saheeh International translation.

(1) And We made it a deterrent punishment for those who were present and those who succeeded [them] and a lesson for those who fear Allah.

(2) Already there has been for you a sign in the two armies which met - one fighting in the cause of Allah and another of disbelievers. They saw them [to be] twice their [own] number by [their] eyesight. But Allah supports with His victory whom He wills. Indeed in that is a lesson for those of vision.

(3) There was certainly in their stories a lesson for those of understanding. Never was the Qur'an a narration invented, but a confirmation of what was before it and a detailed explanation of all things and guidance and mercy for a people who believe.

(4) And indeed, for you in grazing livestock is a lesson. We give you drink from what is in their bellies - between excretion and blood - pure milk, palatable to drinkers.

(5) And indeed, for you in livestock is a lesson. We give you drink from that which is in their bellies, and for you in them are numerous benefits, and from them you eat.

(6) Allah alternates the night and the day. Indeed in that is a lesson for those who have vision.
