Karaite Sage Yefet ben Eli, who lived in Jerusalem during the second half of the Tenth Century said: "...For this is what Anan did, who said 'search diligently in the Torah and do not rely upon my opinion' and Benjamin said in his concluding words "I, Benjamin, am one of thousands and scores of thousands and am not a prophet nor the son of a prophet etc.  So all Karaite scholars used this method and established what appeared to them as truth and encouraged people to search, so much that a man is entitled to disagree with this father and the father will not say to him "why have you disagreed with me?" and a student with his teacher. This is why YeHoVaH forgave them when error befell some of their opinions., and they were absolved because they opened the eyes of men and brought them out of darkness and into light.  Arabic Text: MS Or. 2401 fol.174a -175b at the British Library (IMHM mic. no. 6065) and reprinted and translated in "Medieval Karaism" in The Oxford Handbook of Jewish Studies by Meira Polliack page 314.
