The Importance of Recording Knowledge

A student of knowledge should record what he has learned, especially the rules, guidelines, and rare issues, so that they do not slip away from him. Often, a person recalls a rare issue that is not easily grasped by the slightest reflection,Then he relies on his memory and says: thinking, "I will not forget this, if Allah wills," but he forgets it quickly. So, record the issues, especially the rare ones, or the rules or guidelines, so that you have a reserve.And it has been said: (Record knowledge by writing) and it was said:
Knowledge is game, and writing is its tether. Tether your game with strong ropes.
It is foolishness to hunt a gazelle and then leave it loose among the people.
