The Messenger of God, may God’s prayers and peace be upon him, said: Do not give wisdom to others than it deserves, lest you wrong it, and do not deny it to its people, lest you wrong them. Spending wisdom is the same as its zakat, and it has people, just as zakat has people. If you give wisdom to people other than its people, and you think that it belongs to it, then it is lost, just as this money is lost after giving it. And it did not reach its owner, so he is a guarantor for the one who lost it because he was negligent in that he did not confirm who had lost this wisdom, so he had to give it out again to the one who deserved it so that it would fall into place.
