Muʿjam al-Aḥādīth al-Muʿtabara, Prohibition of Giving Fatwa without Knowledge and Evidence – Ḥadīth #2
[2/-] al-Kafi: Ali b. Ibrahim from his father from Ibn Abi Umayr from Abd al-Rahman b. al-Hajjaj who said: Abu Abdillah عليه السلام was seated in a study-circle of Rabia al-Rayy when a bedouin came and asked Rabia al-Rayy about a matter and he (Rabia) proceeded to answer him, so when he was done (answering) the bedouin asked: is it upon your neck (do you accept responsibility for me following your answer)? Rabia remained silent and did not say anything, so he (the bedouin) repeated the question again and he (Rabia) answered in the same way, so the bedouin said to him again: is it upon your neck? but Rabia remained silent, then Abu Abdillah عليه السلام said to him: it is upon his neck whether he declares it to be so or not, and every giver of Fatwa is liable.
