Sayyidi Ahmad Arabi ash-Sharnubi was born in Sharnub in the Nile Delta near Dasuq. His linage traces back to Sayyiduna wa Mawlana al Imam al Hussayn. Sayyidi Ahmad Arabi ash-Sharnubi travelled widely, staying in Damanhur, living in Mecca and Medina for seven years, founded a Zawiyya in Cairo, and sojourned in Istanbul. He was also a scholar at al-Azhar University. The doctrine of the four major poles (aqtab) can be traced to Sayyidi Ahmad Arabi ash-Sharnubi, where he wrote that there are four grand poles within Sufism to whom all subsequent taruq are attached. He was the heir of the four poles and the Muhammadan light that shines in them. Sayyidi Ahmad is the founder of the Sharnubiyya tariqa. He died in Anatolia in 994AH/1586CE where he is buried.
