Part of a refutation of Darul Ulooms aqeeda:
The isnaad for this 'aqeedah only goes back to Abu Mansoor Al Maatureedee who was an Imaam of Kalaam, Ta'teel and Tahreef and as Dr.Shamsud Deen Al Afghaanee explained in his thesis and impressive research on the Maatureediyyah; that the facts point towards Abu Mansoor taking a large part of his beliefs from ibn Kullaab himself. And Shaykhul Islaam ibn Taymiyyah and Ibnul Qayyim mentioned that he was a follower of Jahm ibn Safwaan.
So is the isnaad that leads back to Allaah equal to the isnaad that leads back to two of most evil individuals in the history of Islaam (i.e. Jahm ibn Safwaan and ibn Kullaab)?
Shaykhul Islaam ibn Taymiyyah mentioned that this individual, Abu Mansoor Al Maatureedee was a follower of the Jahmiyyah (founded by Jahm ibn Safwaan), that evil sect that all of the 'Ulamaa of the past and the present declared to be disbelievers on account of their heresy.
I wish to present to you a great benefit from the rest of this evil isnaad and it is what some of the Scholars mention about Jahm ibn Safwaan: he took his belief from Ja'd ibn Dirham, and it is said that Ja'd took his innovation from Abaan bin Sam'aan, and Abaan took took it from Taaloot, the son of the sister of Labeed bin Al A'asam, and Taaloot took it from Labeed bin Al A'asam, the Jewish Magician, who performed magic upon the Prophet .
(See Ar Radd 'Alal Jahmiyyah of Imaam Ad Daarimee, Majmoo'ul Fataawa, Vol. 5 of Shaykhul Islaam ibn Taymiyyah and Mawqif Ahlis Sunnah Min Ahlil Ahwaa wal Bid'ah, Vol.1)
Abu Mansoor Al Maatureedee, follower of Jahm ibn Safwaan: to Ja'd, to Abaan, to Taaloot, to Labeed, the evil Jew who performed magic on our beloved Prophet (see the tafseer of Suratul Falaq and Naas of Ibn Katheer )
