Umar had some official work done by Abu Ubaida Ibn Jarrah, and afterwards sent him 1000 dinars. Abu Ubaida returned this sum, saying that he had done the work for God’s sake, not for Umar’s, and would not accept any recompense. Then Umar said to him, “We used to be reluctant to accept the gifts the prophet would give us when he sent us off on some mission. But the prophet told us that we should accept them, for they would help us in our religious and worldly affairs. Hearing this Abu Ubaida agreed to accept the money.
