محمد بن سنان عن جعفر بن إبراهيم قال: سمعت أبا عبد الله عليه السلام يقول: من علم موضع كلامه من عقله قل كلامه فيما لا يعنيه وقال أبو عبد الله عليه السلام قال رسول الله صلى الله عليه وآله: إياكم وجدال المفتون فان كل مفتون ملقى حجته إلى انقضاء مدته فإذا انقضت مدته أحرقته فتنته بالنار
4 Muḥammad ibn Sinān narrated from Jaʿfar ibn Ibrāhīm who said, “I heard Abā ʿAbdillāh  say, ‘One who knows the appropriate position of his speech in relation to his intellect reduces his speech about that which does not concern him.’ And Abū ʿAbdillāh  reported that the Messenger of Allah (ṣ) said, ‘Beware of arguing with a deluded individual, for indeed every deluded individual has an  argument that lasts only until his time comes to an end, and when his time is up, his delusion burns him with the Fire.’” [1]
