The word “tudāriʾ,” pronounced with a glottal stop, derives from mudāraʾah, meaning opposition to the truth. If the glottal stop is omitted, it derives instead from mudārāh, meaning to ward off opposition in the best manner (1).
He appointed agents and acted as an agent himself, though he appointed agents more often than he acted as one.
He gave presents, accepted them, and reciprocated them. He also gave gifts and received them. When a slave girl had been allotted to Salamah ibn al-Akwaʿ as his share, he said to him: “Give her to me.” Salamah gave her to him, and he exchanged her with the people of Mecca for Muslim captives (2).
He borrowed with and without collateral, borrowed things for use, and made purchases with both immediate and deferred payment.
He gave a specific guarantee on behalf of his Lord concerning certain deeds, so that whoever performed them was covered by that guarantee. He also gave a general guarantee concerning the debts of Muslims who died without leaving enough to repay them: he would assume responsibility for those debts and repay them. It has been said that this ruling applies generally to rulers after him: the ruler guarantees the debts of Muslims who leave insufficient means to repay them, assuming responsibility for them and paying them from the public treasury. Those who hold this view say: just as the ruler inherits from a Muslim who dies without leaving an heir, he likewise pays that Muslim’s debts if he dies without leaving enough to repay them. Similarly, he provides for him during his lifetime if he lacks the means to support himself.
