Chapter 8 | What Allah (azwj) has Forbidden a Believer to do Against a Fellow Believer
201 - وعن أخي الطربال قال: سمعته يقول: ان لله عز وجل في الأرض حرمات، حرمة كتاب الله، وحرمة رسول الله، وحرمة أهل البيت، وحرمة الكعبة، وحرمة المسلم وحرمة المسلم، وحرمة المسلم.
201. It has been narrated that the brother of al-Tirbal (i.e. Ibrahim ibn Jamil al-Kufi) said: I heard al-Sadiq saying: Allah holds some on the earth as sacred: the Book of Allah, the Messenger of Allah, the Ahl al-Bayt, the Ka'bah and a Muslim and a Muslim and a Muslim. (He repeated thrice).
