How can you benefit from what you read, and how can you retain knowledge?

The scholars say: Do not read unless you have a pen with you.

Do not read unless you have a pen with you, and they say: Knowledge is like game, and writing is its tether.

Secure your game with strong ropes.

It is foolish to catch a gazelle,

then leave it free in the wilderness. So when a person reads, he should have a pen to write down the benefits.

Either in a separate notebook, or on the margins of the book, at the beginning or the end.

These notes are actually the summary of the book.

This is the best way to read: that a person records the benefits he picked up from the book. Allah is the one who helps.

He can also study the book; if he reads it and finds it beneficial, he can teach it to his children or his brothers, or read it with his friends, and so on. Yes.
