A number of our people have narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Husayn ibn Sa’id from Fadalah ibn Ayyub from ‘Abd Allah ibn Bukayr from abu Basir from abu Ja’far (a.s.) who has said the following: “The Messenger of Allah has said, ‘Reviling a believer is a gross sin, fighting him is disbelief, eating his flesh (backbiting) is disobedience and the illegality of consuming his property is like the illegality of spilling his blood (taking his life).”’ وثق كالصحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (11/5))
