After the birth of Khalisa, Sheikh Bilal had changed his seat to a distant village called Chorre in today's Guba Qoricha district of West Harerghe Zone where he became one of the early Muslim scholars who campaigned to Islamize the Ittu Oromo in Guba Qoricha.[3] He then settled at that very place and took his assignments as a chief Islamic scholar with many disciples and a Qadi of the area.
