Ahmed Raza Khan, commonly known as Aala Hazrat, Ahmed Raza Khan Barelvi, or Ahmed Rida Khan in Arabic, (14 June 1856 CE or 10 Shawwal 1272 AH – 28 October 1921 CE or 25 Safar 1340 AH), was an Islamic scholar, jurist, mufti, philosopher, theologian, ascetic, Sufi, poet, and mujaddid in British India. He wrote on law, religion, philosophy and the sciences, and because he mastered many subjects in both rational and religious sciences, Francis Robinson, one of the leading Western scholars of South Asian Islam, considers him to be a polymath.
