Central to the teaching ethos of the iSyllabus, is that all lecturers, whether they be the main instructors or visiting lecturers, faithfully convey mainstream Sunni Islamic teachings, as represented in the main teaching centres of the Muslim world. Through this, students can be safe in the knowledge that what is taught is reliable, and consistently upheld throughout the teaching staff. Central to ensuring this is the system of the teaching ‘ijaza’.

The system of ijaza is a scholarly chain of transmission for each subject, which links each generation of scholars back to the previous ones, and so on all the way back to the source of all guidance, the blessed Prophet, ensuring that the next generation have taken directly from recognised scholars, rather that gleaning pieces of information from books alone.
