The irony is that nomadic Turko-Mongols once they converted to Islam, conquered many lands and many local population converted to Islam because of their rule. It is just the nature of their culture, sedentary and nomadic that makes their character different. Babur was alcoholic and had many other vices, same with earlier turko-mongol warriors/rulers that came to India, but it is because of them and their actions you have 500 million Muslims in South Asia. Sedentary population live in close quarters, go to mosque together and eventually they become more devout, while nomadics live freely in felt tents in the steppe and retain more of their original pre-Islam culture. Timurids and Mughals of India were following Yassa even after they converted to Islam for many centuries:
