Muawiyah I
During his rule, Uthman's military-style was more autonomical in nature as he delegated much military authority to his trusted kinsmen—e.g., Abdullah ibn Aamir, Muawiyah I and Abdullāh ibn Sa'ad ibn Abī as-Sarâḥ—unlike Umar's more centralized policy. Consequently, this more independent policy allowed more expansion until Sindh, in modern Pakistan, which had not been touched during the tenure of Umar.
