Many have written about him, including Sheikh Abdullah Murdad Abu Al-Khair in his book (The Spread of the Bull and the Flower in the Biographies of the Virtuous of Mecca from the 10th to the 14th Century), Volume II. Among them also is Yusuf bin Ismail Al-Nabhani in his book (The Collection of Miracles of the Saints). Muhammad bin Abdulmajeer Al-Siraj also included his biography in his book (The High Paths in the Biographies of the Sayyids of Al-Mirghaniyah). Among them also is Ahmad bin Idris bin Al-Amoudi. He criticized many scholars of his time, including Sheikh Saeed Muhammad Al-Nasih, author of Al-Bayanah, Sheikh Ahmad Abdul Karim Al-Hindi, and Sheikh Al-Azbaki, and others from these sheikhs and scholars. He received five paths from his many sheikhs: the Naqshbandi, Qadiri, Shadhili, Junaydi, and Al-Mirghaniyah, which is the path of his grandfather Abdullah Al-Mahjoub. He built his path on the basis of these five paths. Later, after moving between sheikhs, he ended up with the five paths, which he symbolized with the inscription "JM" in the year 1197 AH / 1783 AD. Sayyid Ahmad bin Idris came to Mecca in late 1197 AH / 1783 AD and stayed there for fourteen years, during which he held circles of knowledge and study, becoming a focal point for students of knowledge from all over the Islamic world. Ibn Idris laid down a number of teachings that were the pillars of his Sufi reformist school. This school carried the banner of renewing religion by calling for the removal of the impurities and innovations and superstitions that had become attached to it. Sayyid Ahmad adopted a methodology based on several principles, which we can summarize in the following points: 1. Following the Book and the Sunnah, while rejecting guidance from any other sources. 2. Paying attention to the interpretation of the Quran, Hadith, and Fiqh, and focusing on education as an effective means of creating the Muslim community. 3. Concentrating on establishing virtuous principles, self-accountability, and creating a Muslim who remembers God. 4. Calling through peaceful and gentle means, and paying attention to spreading the call among non-Muslims, and striving first to build the elite. Al-Mirghani: Muhammad Othman: The same source, p. 4.
