Muhammad Othman (Al-Khatm), who came to Sudan after the death of Sayyid Al-Hasan to assist his paternal uncles. He married Sayyida Fatima bint Sayyid Al-Hasan and contributed significantly to bearing a large part of the military and religious burdens of the Tariqa during the Mahdist Revolution. Finally, there is Sayyid Abdullah Al-Mahjoub, son of Muhammad Badr Al-Khatm II and husband of Nafisa bint Sayyid Al-Hasan, who came from Hijaz to Sudan and remained there until his death. He was buried in the family cemetery in Khartoum Bahri. Sayyid Muhammad Othman Al-Aqrab led the conflict that occurred between the Khatmiyya and the Ansar. He was assisted in this by Sayyid Bakri bin Sayyid Jaafar. The conflict that arose between the two groups was based on the Khatmiyya's lack of conviction in the Mahdism of Muhammad Ahmad bin Abdullah. Rather, they saw him as usurping it and falsely claiming it. It seems they expected the appearance of the Mahdi in a different way. They linked the Mahdi to the Khatmiyya and assigned the Mahdi a specific rank that was frequently mentioned in their literature and that Muhammad Othman (Al-Khatm) mentioned more than once.

They went astray and led others astray. So, God sent the Egyptian government against them, and they destroyed their homes and erased their traces in Suakin, so they lost this world and the hereafter." Muhammad Othman Al-Mirghani Al-Asghar led a fierce resistance against the Mahdi and clashed with it in several battles, including the Battle of Al-Jamam in February 1885 and the Battle of Al-Faqih Issa, and others. Then Sayyid Muhammad Othman decided to...
