Shaykh Allaha Muqbil ibn Hadi al-Wadi said:

مختلفٌ فيه بين أهل السنة ، فمنهم من يراه كافراً ، ومنهم من يراه فاسقاً ، والذي رجحه الحافظ الذهبي – ولعله الصواب إن شاء الله – أنه يعتبر فاسقاً ، وأمره إلى الله .

Ahlesunnah differed in regards to him. And from them who called him Kaafir, and from them who called him Faasiq. And hafidh adh-Dhahabi preferred opinion – which is more correct, inshAllah – that he was Faasiq. And his ruling upon Allah.
