Shaykh ‘Ubayd Al-Jaabiree
Question: How do we deal with one whom some of the scholars have commended due to having good thoughts about him or due to his writing an article about one of the people of innovations; however, his actions contradict that commendation; such as lying and revilement of the Salafees and speaking repugnant words about them; rather, lying on some of the scholars to others of them etc. so what do we do with one who is like this?
Answer: I say: The scholars of Ahlus-Sunnah and their Imaams are not such that revelation descends upon them from the heavens. Rather, they commend who they commend due to what he makes apparent from the Sunnah and defense of it and its people, and circulation of books therein and refuting the opposers. Based upon this, they commend him in accordance with that which he makes apparent.
When he deviates from that and repudiates Ahlus-Sunnah and aligns himself with the people of innovations, and defends them, then they deal with him with that which he is deserving of in that. What you have mentioned from commendation is not something strange. Ash-Shaafi’ee, may Allaah have mercy upon him, used to commend Ibraheem ibn Muhammad ibn Aboo Yahyaa and say: “A trustworthy man narrated to me…” The other scholars besides him criticized him. Imaam Maalik, may Allaah have mercy upon him, was asked about this Ibraheem. It was said to him: “Is he trustworthy?” He said: “No, not even in his religion.”
So the commendation of Ash-Shaafi’ee, may Allaah have mercy upon him, did no harm. Ash-Shaafi’ee is an Imaam according to us and to all those who know his status from the people of Islaam and the Sunnah. However, it did not benefit Ibraheem ibn Aboo Yahyaa, because the scholars criticized him. The principle is: He who knows is a proof against he who does not know.
