Question : And if by devoting himself to knowledge he obtains money from voluntary charity, and he is able to earn a living, what do we say to you?

Answer : No, it is better that he devote himself and take from the voluntary charity. He does not take it on the basis that I am taking it, but he takes it on the basis that I am seeking knowledge, whatever he attains.
