Shouldn't next atleast next 3 PMs of India be necessarily chosen from MUSLIMs(more than 20%)?

Perhaps the free citizens of the world's most populous democracy know better than elect someone whose religion is not compatible with democracy and freedom, whose allegiance is not to India, but to the world wide imposing of Sharia Law and the one world Islamic Caliphate? Unless of course, a Muslim candidate would denounce this teaching directly from the Qu'ran, Hadiths, and Sunnah?
