Abdullah Ghaznavi (1811 – 15 February 1881) was an Afghan-Indian Muslim scholar and pietist. A pupil of Sayyid Nazir Husain, he was exiled from his native Ghazni, Afghanistan on account of his adherence to and propagation of Ahl-i Hadith doctrines and had settled in Amritsar, Punjab, where he soon began attracting his own circle of students and admirers. According to political scientist Dietrich Reetz, Abdullah Ghaznavi represented the ascetic tradition within the leadership of the early Ahl-i Hadith movement in contrast to those who reflected the sect's increasing popularity among the urban elites.
