Aḥmad ibn Muḥammad transmitted to us from Muḥammad ibn Ismāʿīl, from Jaʿfar ibn Bashīr, from Abū Baṣīr, from Abū Jaʿfar (peace be upon him) or Abū ʿAbdillah (peace be upon him), he said:“Do not accuse anyone, who brings a tradition to you of falsehood, for you do not know it [the tradition] may be of the truth, so you would accuse Allah, above His Throne, of falsehood!” [Basaair al-Darajaat, page 558, Hadith 5]

حدثنا أحمد بن محمد عن محمد بن إسماعيل عن جعفر بن بشير عن أبي بصير عن أبي جعفر عليه السلام أو عن أبي عبد الله عليه السلام قال لا تكذبوا بحديث اتاكم أحد فإنكم لا تدرون لعله من الحق فتكذبوا الله فوق عرشه

Al-Sheiḵh ʿAlī ʿĪsa al-Zawwād writes: “They do not know, that, when the Chain (Sanad) is authentic, it is a proof for the servants, because the narration from a truthful one is a proof, and if it (the Sanad) is not authentic, then it is not permissible to deny it, because it might come from the Ahl al-Bayt (peace be upon them), in which case it would be a rejection of them, as has been mentioned in the noble narration.” [Risalah fi l-Khabar al-Dha’if, page 42]
