أحمد بن زين الدين الأحسائي
His early religious instruction was entrusted to "hājjī" Afzal Siyālkōtī (hadith) and "hāfiz" Abd al-Rasūl Dihlawī (Qur'an). At the age of 18, he joined the Naqshbandī order under Nūr Muhammad Bada'ūni, who was closely connected to the teachings of Shaykh Ahmad Sirhindī, and completed his studies in four years. He was also initiated in the Qādirī, Chishtī and Suhrawardī orders.
