Conclusion of the Research This is a summary of the most important findings and facts reached through this study: 1. Sayyid Muhammad Uthman al-Mirghani (al-Khatm), born in the village of al-Salama near Ta'if in 1271 AH/1854 AD and passed away in 1331 AH/1913 AD, belonged to a venerable religious family renowned for its piety, righteousness, and vast knowledge. It was known for its connection to the Household of the Prophet through a lineage documented in the literature of the Mirghanis and affirmed by many great scholars of that era. Muhammad Uthman (al-Khatm) studied under several of his relatives and also under others from whom he acquired knowledge of both the exoteric and esoteric.

2. Sayyid Abdullah al-Mirghani (al-Mahjub), who passed away in 1311 AH/1893 AD, was the direct grandfather of Muhammad Uthman al-Khatm. He was known for his knowledge, piety, and numerous writings.

3. Sayyid Muhammad Uthman al-Mirghani connected with Sayyid Ahmad bin Idris (d. 1253 AH/1837 AD), who instructed him to travel to Sudan to spread his teachings and ideas. Al-Mirghani visited Sudan three times, achieving significant gains from the allegiance of followers and supporters, and establishing extensive influence in northern and eastern Sudan, where he founded his village (al-Sunniya) in al-Taka, which became an important center for the Khatmiyya da'wa.

4. Al-Mirghani faced some harassment during his da'wa mission in Sudan. He incurred the displeasure of rulers and political leaders in the regions of Shendi, Kordofan, and Sennar. This harassment contributed to limiting his influence somewhat in certain parts of these areas. Al-Mirghani also encountered opposition and disagreement from the supporters of the Majzūbiyya tariqa.

5. One of the most prominent reasons for Muhammad Uthman al-Mirghani's remarkable success in the region of Sudan was the capabilities, talents, and advantages he possessed. Al-Mirghani was a noble scholar from a well-known religious family, which enabled him to gain the trust of both the common people and the elite among the Sudanese.

6. Sayyid Muhammad Uthman appointed his son, Sayyid Muhammad al-Hasan, as his deputy in Sudan. He urged him to cooperate with the rulers and to align with them, and not to be like him in his dealings with them, as al-Khatm was emulating Ibn Idris in not approaching rulers or standing at their doors.
