In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Imaam Barbahaaree [rahimahullaah] stated: “If you see a man speaking well of Ibn Abee Du’aad, Al-Mareesee, Thumaamah, Abul Hudhail or Hishaam Al-Footee or any of their adherents, beware of him because he is an innovator. These people were upon apostasy, so leave this man who spoke well of them and whomever he mentioned of them”.
‘If you see a man speaking well of Ibn Abee Du’aad, Al-Mareesee, Thumaamah, Abul Hudhail or Hishaam Al-Footee’
Shaikh Saaleh Al- Fawzaan [hafidhahullaah] commented saying: “If you see a man commending the people of evil and the scholars of misguidance, such as these off shoots of the Jahmiyyah, then know that he is a sinful one, a corrupter and a misguided one, because he praises them not except that he loves them and approves of their path.
And if you see a man commending Ahlus Sunnah, such as the likes of Imaam Ahmad and Ibnul Mubaarak, and likewise commending the Scholars of the Taabi’een and those who came after them, then know that he is a good person, because he commends not Ahlus Sunnah except that he loves the Sunnah and holds unto it.
This teaches us a lesson [due to the fact that] some of the brothers or some of the students of knowledge commend some of the innovators or the people of desires and deviated views, whilst not examining their views and orientations. They attack and find fault with the people of goodness; because they lend an ear to those who find fault with them and believe them. This is a severe danger.
If you find fault with the good people – the people of knowledge and Ahlus Sunnah- and commend the people of deviated views and orientations, then this is a severe danger even if you do not sit with them.
