I asked al-Hasan al-Basree about something, and said [to him]: The jurists are saying such-and-such.
The fuqahaa of Madeenah [were]: Sa’eed ibn al-Musayyib, ‘Abdul-Malik [ibn Marwaan], ‘Urwah [ibn Udhaynah], and Qubaysah ibn Dhu’ayb.
I have not seen a man more knowledgeable about [matters of] halaal and haraam than Sufyaan ath-Thowree.
Suhnoon was asked whether it is possible for a scholar to say ‘I do not know’ in response to a matter he knows about?
It is befitting for the scholar to bequeath his companions the term ‘I do not know’, so it becomes a principle to which they seek refuge [from the danger of speaking without knowledge].
