Muawiyah established Umayyad rule over the Arabs after the first First Fitna in 661 AD, and resumed expansion of the Muslim Empire. After 663/665 AD, the Arabs launched an invasion against Kapisa, Zabul and what is now Pakistani Balochistan. Abdur Rahman b. Samurra besieged Kabul in 663 AD, while Haris b Marrah advanced against Kalat after marching through Fannazabur and Quandabil and moving through the Bolan Pass. King Chach of Sindh sent an army against the Arabs, the enemy blocked the mountain passes, Haris was killed and his army was annihilated. Al-Muhallab ibn Abi Sufra took a detachment through the Khyber pass towards Multan in Southern Punjab in modern-day Pakistan in 664 AD, then pushed south into Kikan, and may have also raided Quandabil. Turki Shah and Zunbil expelled Arabs from their respective kingdoms by 670 AD, and Zunbil began assisting in organizing resistance in Makran.
