ʿAbd al-Ḥaqq al-Dehlawī (1551–1642) was one of the most influential Islamic scholars of Mughal India, renowned primarily as a muhaddith who laid the foundations of hadith scholarship in the Indian subcontinent. Born in Delhi, he travelled to the Hijaz, where he studied hadith extensively in Mecca and Medina before returning to India to revive rigorous hadith studies. He was affiliated with the Qadiriyya Sufi order, yet firmly grounded in Sunni orthodoxy. Al-Dehlawī authored numerous works in Arabic and Persian, including commentaries on hadith, biographies of scholars, and treatises that integrated fiqh, hadith, and tasawwuf without diluting doctrinal discipline.
