Is it permissible for a Muslim to give away all of his wealth in charity?

Question : I say: We have mentioned previously that if Allah bestows wealth upon a person, he should not spend it here and there, because he does not know who will recognize the value of the wealth.

Answer : No, we did not say that. No, we said that if a person knows from himself that he has strong reliance upon Allah (tawakkul), then there is no harm, just as Abu Bakr (may Allah be pleased with him) did, just as Abu Bakr did. But as for the person who knows from himself that his reliance is weak, he should not spend all of his wealth.
