Under this scale, Umar's son Abdullah ibn Umar got an allowance of 3000 dirhams, while Usama ibn Zaid got 4000. The ordinary Muslim citizens got allowances of between 2000 and 2500. The regular annual allowance was given only to the urban population, because they formed the backbone of the state's economic resources. The Bedouin living in the desert, cut off from the state's affairs, and making no contributions to development, were nevertheless often given stipends. On assuming office, Uthman increased these stipends by 25%.
