Syed Nazeer Husain Dehlawi (1805 – 13 October 1902) was an Islamic scholar and leader of the reformist Ahl-i Hadith movement in India. Earning the appellation shaykh al-kull (teacher of all, or the shaykh of all knowledge) for his authority among early Ahl-i Hadith scholars,[2][3] he is regarded, alongside Siddiq Hasan Khan (1832–1890), as the founder of the movement[4][5][6] and has been described as "perhaps the single most influential figure in the spread of the Ahl-i-Ḥadīth".[5]
