Muhammad bin Qasim
From Debal, Muhammad Bin Qasim attacked Nayrun Kot (present day Hyderabad) and the locals, equipped mostly with farming implements, surrendered. King Nayrun was dethroned. The army of Muhammad Bin Qasim looted the trade goods and took over the Hindu worship sites atop the Ganjo Takker ridge, building mosques to replace them. The Nayrun Kot was destroyed. After that, he captured Sadusan (Sehwan). Again, the main temples were razed and mosques were built to replace them, often using their components; additionally one-fifth of the booty including slaves was dispatched to Hajjaj and the Caliph. At Ar-rur (Nawabshah), he defeated Raja Dahir's forces and the eastern [Jats] in the battle. About 6000 Sindhi warriors were put to death. Dahir's wife Ladi committed "suttee" to escape from the hands of the Muslims. Aror was the capital of Sindh which was ruled by Raja Dahir. Muhammad bin Qasim won over Raja Dahir and took control of Sindh. His conquest for the Umayyads brought Sindh into the orbit of the Muslim world.
