graduate in Islamic Studies from Sindh University, Pakistan. Spiritual education He received Ijazah of Naqshbandi tariqah from his father, Sheikh Sohna Saeen who was the chief caliph and successor of Abdul-Ghaffar Naqshbandi of Larkana, Sindh. His father trained him in the spiritual path of Naqshbandi Mujaddidi tariqah from the childhood, and permitted him to teach the tariqah to his followers. He received Ijazah three times from his father. Once he received Khilafat (syn. of Ijazah in tariqah) in 1397 A.H when he was still studying in madrasah. Second time he received Khilafat when his father was awarding Khilafat to another person Maulana Siddiq Ahmad Nasir. Third time he received Khilafat in 1403 A.H (the year his father died) along with Maulana Naseem Ahmed of Hyderabad. During the last years of his father, he used to represent his father and presided various programs and gatherings where he initiated newcomers in the tariqah. His father used to send him in his place. Succession After the demise of Khwaja Allah Bakhsh Abbasi all the Islamic scholars, khalifas (spiritual representatives) and key persons of the organization unanimously agreed to nominate his son Khwaja Muhammad Tahir as successor. He is also known as Sajjan Saeen. On that day almost every follower took Oath of Allegiance on his hand except for a few who also took Oath of Allegiance later. Some of them had reported that Khwaja Allah Bakhsh came in their dream and advised them to take Oath. Some other had spiritual sightings of Muhammad who guided them to take the oath of allegiance with Shaikh Muhammad Tahir, as reported in the book Seerat Wali-e-Kamil. His tariqah Spiritual chain of succession Shaikh Muhammad Tahir belongs to the Mujaddidi order of Sufism, which is the main branch of Naqshbandi Sufi tariqah. His spiritual lineage goes to Muhammad, through Shaikh Ahmad Sirhindi, the Mujaddid of eleventh Hijri century. Sufi methodology The Shaikh focuses on Qalbi Zikr (a method of remembering Allah by heart), which makes the base of his tariqah. He advises his murids or spiritual students to practice Muraqbah daily, which is a kind of meditation for the Qalbi Zikr. The collective Zikr or Muraqba is held daily after the Fajr prayer in all the centers of the organization. The shaikh himself leads the Muraqba at Dargah Allahabad sharif daily where he himself resides. This collective Muraqba is different from other branches of the Naqshbandi tariqah.
