All his while,the young invader was keeping in close contact with Hajjaj, soliciting the latter's advice even on the smallest matters.so efficent was the communication system that letters were written every three days and replies were recieved in seven days. so that the campaign was virtually directed by the veteran Hajjaj ibn yusuf himself when siege of Debal continued for some time a infecter informed Muhammad bin Qasim How the temple could be captured.Thereupon the Arabs,planting their ladders stormed the citadel-Temple and swarmed over the walls.As per Islamic injuctions, The inhabitants were invited to accept Islam.The carnage lasted for three days.The temple was razed and a mosque built.At Ar_rur bin Qasim met Dahir's forces in the battle but he defeated Dahir and dahir died.Muhammad bin Qasim captured the sindh.
