Musannaf Ibn Abi Shayba 33:544

Muhammad ibn Fudayl narrated to us, from al-A’mash, from ‘Abdullah ibn al-Sa’ib, from Zadhan, from al-Bara’ who said: "Indeed, Allah commands you to render trusts to whom they are due." He said: The trust is in prayer, and the trust is in washing from major ritual impurity (janabah), and the trust is in measuring, and the trust is in weighing, and the greatest of that is in deposits.
