Uthman spent liberally in the way of God. He purchased the Bir Rauma well from a Jew and dedicated it to public use. He financed the project for the extension of the Prophet's mosque. He met a greater part of the expenses for the financing of the expedition to Tabuk. In the event of a famine the traders in Madina offered to purchase his stock of food grains after allowing him considerable profit. He distributed the entire stock among the people free, and declared that thereby he would earn a ten times profit from God. which no merchant could offer him.
