You stated in your inquiry that some of this had reached your hearing from scattered books and indications that follow one another in parts and fragments.

I have desired to favor your quest and fulfill your choice and answer your question, seeking reward and fearing punishment, as Allah, Mighty and Majestic, said: {And do not conceal testimony, for whoever conceals it—his heart is indeed sinful} ¹ and He, Mighty and Majestic, said: {And whoever is stingy is only stingy toward himself} ² .It has been narrated from the Knower (al-‘Alim), may His Might be exalted, that he said: "Do not withhold wisdom from its people, for then you would wrong it; and do not give it to those who are not its people, for then you would waste it. Do not withhold wisdom from its people, for then you would wrong them; and do not give it to those who are not its people, for then you would wrong it."
