How did internal religious divisons destabilize medieval India?

The territory of India, in the 8th - 9th centuries, was subjected to frequent attacks by Arabs and Muslim Turks. As a result of these seizures, in 1206, a large Muslim state was formed - the Delhi Sultanate. Neither in the ancient nor in the medieval history of India did its religions become the basis for the creation of a strong centralized state. The Sultanate in India has existed for more than three centuries - for the Indian state, this period is huge. It would be more durable if the entire population of the country was entirely Muslim. The constant confrontation between Hinduism and Islam weakened the state. The reason for the disagreement between the largest religions of India lies in the very nature of Islam and Hinduism, as well as in the traditions, beliefs, and values generated by these religions. The incompatibility of living standards and value systems led to conflicts, weakening of the habitually strong Islamic statehood. This could not but affect the internal unity of the Sultanate, where Hindu rebellions often flared up.
