guys. First of all, a brief reminder, it's dangerous to speculate and start taking that speculation as "facts". Please don't make it a culture to speculate and make open blanket statements without studying the matter first. That's not what the Prophet taught us. Hindu and polytheists are many in Malaysia not because sahaba didn't conquer the place to spread Islam. Hindu and polytheists are many in Malaysia because they were brought in by the British colonialist in the 1900s. Indeed, Hindu and polytheists were majority in the peninsular during 1940s before Japanese conquered the land from British. Only after that Muslims started becoming majority again. Indonesia was the major land for Hindus since eon agos. That's why the largest (or one of the top 5 largest) temple is in Java Island. And Hindu still is prevalent in especially Bali Island. But majority of the land was converted into Islam with da'wa lead by Muslims from Yemen. Regarrding Shafi'i in Malaysia, the lifestyle is "dilluted" through British based education system. However there are efforts to revive the madrasa school system again (quite a number of new madrasas are already in operation). Indeed, if you study the history of the area, during the 1800s till 1940s, there were a few ulama who were quite famous from the area, mostly from Pattani area (Southern Thailand where the Muslims are waging jihad there to liberate the land and to apply sharia law).
