عبد المؤمن بن علي
While young, Abd al-Mu'min went to Tlemcen to learn the Fiqh. His tutor died before he could complete his study. He then was made aware of a learned and pious Faqih called "Feqih Soussi" (later known as Ibn Tumart) who was travelling from the east on his way to his native land in Tinmel, Morocco. Abd al-Mu'min and his peers wanted to convince Ibn Tumart to settle in Tlemcen, so he was sent to Ibn Tumart with a letter from the students inviting him to come to their land. The two met at Mellala near Bejaïa. Ibn Tumart turned down the invitation, but Abd al-Mu'min stayed with him and they continued the journey together to Morocco.
