The Diwan of Shaykh Muhammad Said al-Jamal ar-Rifa'l ash-Shadhuli is in the tradition of the mystics of Islam. To understand his teachings and his poetry, it is necessary to enter his world, the world of al-Islam, the real Islam, the religion of the Unity of the Prophet Muhammad, may the peace and blessings of Allah be upon him, who brought the light and the mercy to all, and to surrender to the Light of the religion in the path of the Sufi way taken by all the beloveds who have come before.
