Barefoot entry and gentle debate marked medieval Qur’anic schools.

Evidence

But in their common schools, where the Qur’an is expounded … they never enter, except barefoot. Therefore the master who expounds, as much as the pupils who listen, leave their shoes outside, and go into the schools barefoot; and there they read and dispute with the greatest gentleness and moderation. — Norman Daniel, Islam and the West, 1203
