After having dealt with the Arabs of eastern Arabia, he continued his expedition into western Arabia and Syria, where he attacked several cities—he even went as far as Medina.[3] Because of his cruel way of dealing with the Arabs, he was called Dhū l-Aktāf "he who pierces shoulders" by them.[4][6] Not only did Shapur II pacify the Arabs of the Persian Gulf, but he also pushed many Arab tribes further deep into the Arabian Peninsula. Furthermore, he also deported some Arab tribes by force; the Taghlib to Bahrain and Hatta; the Banu Abdul Qays and Banu Tamim to Hagar; the Banu Bakr to Kirman, and the Banu Hanzalah to a place near Hormizd-Ardashir.[4] Sasanian garrisons were established in Oman's strategic coast in Al Batinah Region, including the tip of the Musandam Peninsula, Sohar, and Rustaq.[7] Shapur II, in order to prevent the Arabs from making more raids into his country, ordered the construction of a wall near al-Hirah, which became known as war-i tāzigān ("wall of the Arabs").
