Abul Hasan Ali Hasani Nadwi (24 November 1914 – 31 December 1999) also spelt Abul Hasan Ali al Hasani an Nadvi (known affectionately 'Ali Miyan') was an Indian Islamic scholar and author of over fifty books in various languages. He was a theorist of the revivalist movement. Maulana Ali Nadwi sincerely and staunchly believed that the real threat to the modern world, especially the Muslim world, is neither the lack of material development nor the political disturbances, rather it’s the moral and spiritual decline. He firmly believed that Islam alone has the ability to overturn this and thus Muslims must wake up to make an effort in this regard. By staying back, he argued, the Muslims were not only failing themselves rather the entire humanity.
