Following the request of some residents to speak about his religious education, he opened his own Shiite-oriented pesantren, Misbahul Huda, in the village of Nangkernang. In 2006, a kyai and other
Sunni leaders of Nangkernang began to object to the presence of the Shiite school, calling it a "deviant sect", and in April 2007, a protest against the school's celebration of the birth of
Muhammad was attended by thousands. In 2009, Tajul's brother Roisul left the Shiites to become a
Sunni, and began to speak against Tajul. Tajul attributed Roisul's anger to a conflict over a woman Roisul had wanted to marry, while Roisul stated that the conflict stemmed from Tajul's proselytizing. The resulting conflict was settled by the mediation of the
Indonesian Ulema Council. Several Sunni
ulama demanded that Tajul sign an agreement that he would not proselytize, but Tajul refused. ==Arson attack==
