The Debal incident refers to the Arab conquest of Sindh, which began when pirates plundered a ship carrying gifts from the King of Ceylon to the Umayyad caliph. Walid bin Abdul Malik (reigned 705–715 CE) was the sixth Umayyad caliph who authorized the punitive expedition led by Muhammad bin Qasim. This campaign resulted in the conquest of Debal and the establishment of Muslim rule in Sindh in 711–712 CE.
Walid bin Abdul Malik was the son of Abdul Malik bin Marwan and the sixth ruler of the Umayyad dynasty. His reign is considered the peak of Umayyad power, marked by territorial expansion both in the East (Sindh under Muhammad bin Qasim) and the West (Spain under Tariq bin Ziyad). He also commissioned the construction of the Great Mosque of Damascus (Umayyad Mosque). The Debal incident occurred around 710–711 CE when Arab pirates seized a ship near the Sindh coast, and Raja Dahir of Sindh refused to return the plundered goods, prompting Walid to send Muhammad bin Qasim.
