neither Gazwa-e-Hind nor Islam as one true religion was not cause or even ideas behind partition. And speaking about Gazwa-e-Hind, while conveniently ignoring Akhand Bharat, is pure propaganda. If you read about Jinnah in old school history books which unfortunately are being edited out by NCERT in India, he was never was religiously motivated. His idea was Muslim population would be a minority in Hindu controlled state, which wasn't far fetched, look at Indian politics right now, which runs on the basis of Muslim hatred. Also claiming things like Gazwa-e-hind(Ignoring Akhand Bharat) and Muslims believing in one true religion and then saying India is tolerant or Muslims and secular becomes an Irony. You can't run both ways. Also the violence during partition were on both sides, not just one side.
