Syed Ahmad Ullah (or Syed Ahmad Ullah Maizbhandari) (14 January 1826 – 23 January 1906) was a Bangladeshi Sufi saint and founder of the Maizbhandari Sufi Order, the first such order to originate in Bangladesh.
Birth and family chain
In 1826, Syed Ahmad Ullah Maizbhandari was born in Maizbhandar, Chittagong in Bangladesh. His father was Syed Motiullah Maizbhandari and mother was Syeda Khayrunnesa. Ahmad Ullah's predecessor Syed Hamid Uddin, was appointed as the imam and judge in Gauda. Because of the epidemic in Gauda, he settled in Kanchannagar of Patiya thana in Chittagong.  One of his sons, Syed Abdul Quader was appointed as the imam in Fatikchhari. His great grandson Syed Motiullah settled in Maizbhander.
Ahmad Ullah founded the Tarika-e-Maizbhandari or the Maizbhandari Sufi order, a Sufi Tariqa (religious order) based in Chittagong District. A research report prepared by the Migration Review Tribunal (MRT) and Refugee Review Tribunal (RRT) of Australia reported the order today has over ten million followers.
Saifuddin Ahmad Maizbhandari is the order's current leader.
According to German scholar Hans Harder, the order based in Maijbhandar "is a powerful religious institution whose very popularity and influence defy any notions of marginality. It has been able to draw adherents from all sections of society, including the urban middle class, and have managed to assert their perspective on Islam vis-à-vis pressure from reformist quarters while keeping in touch with the religious mainstream in Bengal."
In terms of literature, there has been "a sizeable textual output from within the movement since the beginning of the twentieth century, including hagiographies and theological treaties, in the form of monographs, leaflets and journals". 
The order is known for its gatherings for spiritual listening and devotional music, which are important in Bengali Sufi traditions. There are over 10,000 such songs, transmitted orally at first but now on CD and video, and they have come to form their own distinct genre of music in Bangladesh.
