The Ruling on One Who Doubts That the People of the Sunnah Are on the Truth

The questioner:
And O Shaykh, inform us, may Allah reward you, about what remains. He said, Exalted is He: If we were to call upon them, perhaps they are the ones who are on the right path.

The Shaykh:
He said.

The questioner:
'Abdullah ibn 'Umar said: You do not say, "Perhaps we will say your Prophet is with your brothers," because Allah says to you: "Your religion is yours, and my religion is mine," except that he is arguing with the people of the Sunnah and appears to be calling to Allah. And if he intends disbelief in what he said, then the Prophet of Allah has informed you, O Allah.

The Shaykh:
This is very serious speech, and no Muslim can bear it. However, the door of repentance is open. He must hasten to repent to Allah, the Exalted, with a valid repentance, and he must restrain his tongue from such speech. Otherwise, his ruling is the ruling of the Rafidah, because he justified what they are upon and endorsed what they are upon, and he doubted the methodology of the people of the Sunnah. He does not know whether they are the ones on the truth or the Rafidah. This is clear apostasy.
