Gurjara king Siluka repelled Arabs from "Stravani and Valla", probably the area North of Jaisalmer and Jodhpur, and the invasion of Malwa but were ultimately defeated by Bappa Rawal and Nagabhata I in 725 AD near Ujjain. Arabs lost control over the newly conquered territories and Sindh due to Arab tribal infighting and Arab soldiers deserting the newly conquered territory in 731 AD. Al Hakam b. Awana Al Kalbi recovered Sindh, and in c733 AD, founded the garrison city of Al Mahfuza ("The Well Guarded") similar to Kufa, Basra and Wasit, on the eastern side of a lake near Brahmanabad. Hakam next attempted to reclaim the conquests of Junaid in Al Hind. Arab records merely state that he was successful, Indian records at Navasari details that Arab forces defeated "Kacchella, Saindhava, Saurashtra, Cavotaka, Maurya and Gurjara" kings. The city of Al Mansura ("The Victorious") was founded near Al Mahfuza to commemorate pacification of Sindh by Amr b. Muhammad in c738 AD. Al Hakam next invaded the Deccan in 739 AD with the intention of permanent conquest, but was decisively defeated at Navsari by the viceroy Avanijanashraya Pulakeshin of the Chalukya Empire serving Vikramaditya II. Arab rule was restricted to the west of Thar desert. When the Abbasid Revolution overthrew the Umayyads in 750 AD after the Third Fitna, Sindh became independent and was captured by Musa b. K'ab al Tamimi in 752 AD. Zunbil had defeated the Arabs in 728 AD, and saw off two Abbasid invasions in 769 and 785 AD. Abbasids attacked Kabul several times and collected tribute between 787 AD - 815 AD and extracted tribute after each campaign. Abbasid Governor of Sindh, Hisham (7 in office 768 - 773 AD) raided Kashmir, recaptured parts of Punjab from Karkota control, and launched naval raids against ports of Gujarat in 758 and 770 AD, which like other Abbasid Naval raids launched of 776 and 779 AD, gained no territory. Arabs occupied Sindian (Southern Kutch) in 810 AD, only to lose it in 841 AD.
