حدثنا محمد بن موسى بن المتوكل - رضي الله عنه - قال: حدثنا علي بن إبراهيم بن هاشم، عن أبيه، عن ابن أبي عمير، عن عبد الله بن سنان، قال: قال أبو عبد الله عليه السلام: ليس بينكم وبين من خالفكم إلا المطمر. قلت: وأي شئ المطمر؟ قال: الذي تسمونه التر فمن خالفكم وجازه فابرؤوا منه وإن كان علويا فاطميا.
2.	We were told by Muhammed bin Musa bin Mutawakkil, may Allah be pleased with him, that he said: We were told by Ali bin Ibrahim bin Hashim, from his father, from Ibn Abi ‘Umayr, from Abdullah bin Sinan, that he said: Abu Abdillah, peace be upon him, said: Between you and between those who oppose you, there is nothing but the plumbing line. I said: And what thing is the plumbing line? He said: That which you call a plumb. Hence, whoever opposes you and crosses it, then dissociate from him, even if he is an Alawite and Fatimid.
