On silence Except when Speaking what is Good, Abandonment of what does not concern one, and Slander

4 Muḥammad ibn Sinān narrated from Jaʿfar ibn Ibrāhīm who said, “I heard Abā ʿAbdillāh عليه السلام 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 عليه السلام 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]
