✒ ‘Aqeedah Benefit

A man asked Imām Aḥmad Raḥimahullāh: “Can I pray behind an alcoholic?”,

He replied: “No.”

Then he asked: “So can I pray behind one who says ‘Qur’ān is created’?”

Imam Aḥmad said: “SubhānAllāh, I prohibited you from (praying behind) a Muslim then you ask me about a *KĀFIR*?!!”

Sh. Ibn Bāz Raḥimahullāh:

“Ahlus-Sunnah Wal Jamā’ah have gathered upon the belief that Qur’ān is the Speech of Allāh, sent down *UNCREATED*, it commenced from Allāh and shall return back to Him so whoever says ‘Qur’ān is created’ has thus DISBELIEVED.”

Look at the understanding of the Imām of Sunnah Aḥmad b. Ḥanbal Raḥimahullāh, he made Takfeer upon the one whose Bid’ah exceeded the limits of Eemān but he did not make Takfeer of a sinner from amongst Muslims.
