What is the interpretation of the saying of Allah the Exalted, “And as for the questioner, do not drive him away,” and are we obligated to give charity if we doubt the truthfulness of the questioner?

Question:
Honorable Shaykh, may Allah grant you success. He says: What is the interpretation of the saying of Allah, Glorified and Exalted is He, “And as for the questioner, do not drive him away”? Yes, and are we obligated to give charity to the questioner, even if we have doubt about their truthfulness?

Answer:
“And as for the questioner, do not drive him away.” The questioner is of two types: the one who asks about knowledge. You do not drive him away; rather, you answer him with what you know and what Allah has given you of knowledge. The second is the one who asks for money. The one who asks for money is, by default, in need, unless you know that he is not in need, in which case you do not give to him and you advise him. As for if you do not know, the default is that he has a right, and that he is . Yes.
