Mohammed Uthman al-Mirghani al-Khatim

Mohammed Uthman al-Mirghani, known as Al-Khatim, was the founder of the Khatmiyya sufi tariqa that has a following in Egypt, Sudan, Eritrea, Somalia and Ethiopia.

He was born into the Mirghani family in Mecca which was one of the most noble families that have descended from the Islamic prophet Muhammad. He is the son of Muhammad Abu Bakr who is the son of AbdAllah al-Mahjoub who is the son of Ibrahim who is a descendant of the Prophet Muhammad. The lineage of Muhammad Othman al-Mirghani was verified by Murtada al-Zubeidi and this was further verified by al-Jabarti in his book Taareekh al-Jabarti / al-Jabarti's History part two.

Muhammad Othman al-Mirghani was born in Ta'if and died in Mecca and was buried there in AlMa'alla.

His sons followed in his footsteps after his death, the most famous of whom were Muhammad al-Hassan al-Mirghani, Gaafar as-Sadig al-Mirghani, Abdullahi al-Mahjoub al-Mirghani, Hashim al-Mirghani and Sirr al-Khatim al-Mirghani.

AlKhatim's religious journey began in Mecca from whence he travelled to Tarim in Yemen and then to Somalia by sea and to Massawa on the Red Sea coast where he travelled inland into the Ethiopian hinterland before returning to Mecca. On this trip tens of thousands of people embraced Islam including entire clans and tribes.

His second trip started from the Egyptian countryside south of Cairo and he was accompanied by his teacher Ahmad ibn Idris who parted ways with him in AlZeyniyyah. AlKhatim traversed the Nubian lands of the Mahas and the Sakot and went to Kordofan and reached the lands of the Fur people and the Borno tribe. He then travelled to Sennar on the banks of the Blue Nile and then to Shendi via Gezira and via the Butana to the Taka Mountain region near Kassala from which he entered into Ethiopia and visited many regions before returning to Mecca.
