Musannaf Ibn Abi Shaybah

Hazrat Ja'far bin Sulaiman narrates that some of our companions related to us, saying that Hazrat Mawraq 'Ajli used to engage in trade and would acquire wealth. But not even a single Friday would pass before none of that wealth remained with him. The narrator says: If any of his brothers met him, he would give him four hundred, five hundred, or three hundred and say, "Keep this with you for us until we need it." Then, when he met him again, he would say, "You keep it." The other person would say, "I do not need it." Upon this, he would say, "By God! We will never take this money back. You keep it."
