This is one of the reasons Abul Ḥasan was declared an innovator.

If you understand this, then know that there is another INCORRECT generalisation that also requires similar restrictions. That is, “whoever does not declare a disbeliever to be a disbeliever is also a disbeliever.” In fact, this generalisation is even more dangerous than the first, as it leads to chain takfeer! Therefore, as with the previous case, this generalisation must be restricted. Here are additional examples (keep in mind that the earlier-mentioned restrictions have already been applied): ⤵️ Al-Imām ‘Abdul-‘Azīz Ibn Bāz ( رحمه الله) was asked: الذي يثني على أهل البدع ومدحهم هل يلحق بهم؟ “May Allah grant you goodness O Shaikh. The one who compliments Ahlul-Bid’ah and praises them, is he counted among them?” He responded: نعم، لا شك، أن من أثنى عليهم ومدحهم هو داع لهم، يدعو لهم هذا من دعاتهم، نسأل الله العافية “Yes. No doubt. The one who compliments them and praises them is a caller to them. He invites to them. This one is from their callers — and we ask Allah for well-being.” (Ref: Ta’līq Al-Imām Abdul-Azīz Ibn Bāz ‘alā Kitāb Fadl Al-Islām)
