Under the guidance of Aang Endang, many religious scholars (known as ajengan in Sundanese culture) returned to study with him, including those who already operated their own Islamic boarding schools. They devoted their time to studying the same religious texts they had previously learned while in the pesantren.
Sheikh Ahmad Shohibul Wafa Tajul Arifin RA was one such student of Pondok Pesantren Daarul Falah during the leadership of KH AA Fachrudin. He later became a prominent leader of the Qadariyah Naqhshabandiyah Tariqah (TQN) and led the Suryalaya Tasikmalaya Islamic Boarding School. The patience and dedication of KH Aa Fachrudin resulted in one of his students becoming a significant and influential scholar, well-known among many.
Much like his predecessors and parents, Aang Endang also became an influential scholar of his time. His teachings attracted not only the children of students but also many other religious leaders who sought to deepen their understanding of the faith. His influence extended beyond the realm of Islamic boarding schools, as many visitors from various elite backgrounds, including government officials, business leaders, and military personnel, sought his spiritual guidance and blessings through his prayers.
One notable example is General H M Soeharto, the second President of Indonesia, who visited Pondok Pesantren Daarul Falah on several occasions. Despite his demanding role as the country’s leader at the time, Soeharto took the time to meet with Aang Endang and request his prayers. Numerous accounts affirm that President Soeharto regarded Aang Endang as his spiritual mentor, even inviting him to visit the Presidential Palace on several occasions.
