Is it permissible for one who is tasked with paying a specific amount to the needy to spend that money on himself, since he is in need?

Question:
A man tasked me with giving money to a needy student of knowledge, and he said, "Take it yourself if you are in need." So I took some of it, and the rest remained. Is it permissible for me to take the rest, knowing that I receive a salary of about four hundred riyals, and the rest with me is one hundred riyals?

Answer:
It is permissible with two conditions. First, that he gave you permission to do so, saying, "If you are in need, take it; otherwise, give it to so-and-so," and you are in need such that you should take it. This is the condition that he gave you permission. The second condition, which we pointed out, is that you must be in need. As for if you are wealthy, it is not permissible for you to do this. If you have what suffices you, it is not permissible for you to take the charity intended for the poor. Yes.
