Shaykh Rabīʿ ibn Hādī al-Madkhalī:

If your shaykh erred and due to this another shaykh criticised him –as the truth is with this other shaykh, then align yourself with this other shaykh and advise your shaykh.

Do not be a bigot, it is not permissible for you to obstinately stick to the mistakes of your shaykh. If it is that you are a bigot in favour of him [then I say to you], Shaykh al-Islam likens this to a characteristic of the Tartars; this is merely bigotry from the times of pre-Islamic ignorance.

Islam and the Salafī methodology are free from this and it is only upon the Salafī methodology that we nurture [our students]. We declare to Allāh ﷻ our innocence from an education that opposes this education which Allāh is pleased with and has legislated for us.

If Ibn Bāz and Ibn Taymiyyah erred and someone rightfully critiqued them, do not become annoyed and obstinately stick to their mistakes. He critiqued them upon knowledge and evidences seeking the face of Allāh ﷻ  so do not say: “this man criticises Ibn Bāz or Ibn Taymiyyah” (so long as) he critiqued them upon truth, with manners and respect; because the aim is to connect the people to Allāh’s ﷻ methodology, we do not connect them to the mistakes of humans, regardless of who he is. Even if a companion erred, we do not accept his error.
