When and how did Islam spread in Sindh during Muhammmad bin Qasim period? Genious can only answer​

Answer 1

The Arab conquest of Sindh by Muhammad Bin Qasim in 712 AD gave the Muslims a firm foothold on the sub-continent.

Islam came to the Southeast Asia, first by the way of Muslim traders along the main trade-route between Asia and the Far East, then was further spread by Sufi orders and finally consolidated by the expansion of the territories of converted rulers and their communities.
