The Permanent Committee sent me two copies of a book by mistake, so what should I do with the second copy?

Question:
May Allah reward you, Honorable Shaykh. He says: I asked the Permanent Committee about the rulings on songs, so they sent me a copy of the book *Al-Radd 'ala Abi Turab*, and then they sent it to me again. The question is: Am I required to return the second copy to them, or is it permissible for me to give it as a gift to one of the Muslims?

Answer:
No, give it to the one who needs it; there is nothing wrong with giving it to whoever needs it, because the intention is to spread the book and benefit from it. Yes, and this is an endowment (waqf); if you have no further need for it, give it to the one who will benefit from it.
