Abu ‘ Abd Allah (a.s.), said, ‘Was it optional or obligatory Tawaf?’ If it was obligatory Tawaf he had to drop what he had performed to start all over again, but if it was optional and if he was certain of performing three and had doubt about four, he could consider it three; it is permissible.’” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (8/40))
