Hadhrat Mawlānā Qārī Ghulām Husain Kānpurī Naqshbandī Mujaddidī was one of the notable deputies of Khwāja Muhammad Sirāj ad-Dīn Naqshbandī (1297-1333 AH) of Mūsā Zaī Sharīf, Derā Ismāīl Khān district, Pakistan.
He was a notable scholar of Islamic sciences. He was also a reputed reciter (Qārī) of the Holy Qurʾān and knew the seven well known narrations of recitation (Qirāʾāt). For seven years, he served as Imām in the daily prayers for Khwāja Muhammad Sirāj ad-Dīn at the khānqāh as well as during journeys.
After completion of his spiritual perfection, the shaykh awarded him deputyship and sent him to Kānpur for spreading the tarīqah. There, he was soon crowded with seekers and had to establish a mosque and center for his followers. He used to lead the daily prayers himself as Imām. The mosque would get full with the people seeking to receive his blessings.
His Qurānic recitation was so sweet and beautiful, even the prostitutes would come to listen to it and pray Fajr in the back of the masjid, and would repent from their sins and live a pious life.
