“This is concerning my question before abu ‘Abdillah (a.s.), about the case of a man who has a share of water with a people in a canal as partners, and certain ones among them stand free of need of their share of water; if he can sell his share. He (the Imam) said, ‘Yes, he can do so, he can sell it in exchange for wariq (dirham) or if he likes, he can sell for a measure of wheat.’”
