The Muslim's statement to the Christian that "You are not disbelievers in the Qur'an"

The questioner:
He says: Honorable Shaykh, may Allah grant you success. He says: A Christian asked a Muslim man and said to him, "Are we disbelievers?" This Muslim replied to him, "You are not disbelievers in the Qur'an," and he knew that he was wrong, but he lied about the religion of Allah,

The Shaykh:
trees.

The questioner:
He says: A Christian asked a Muslim man and said to him, "Are we disbelievers?" This Muslim replied to him, "You are not disbelievers in the Qur'an," and he knew that he was lying and did so intentionally. He asks: Did he leave Islam by saying this?

The Shaykh:
He does not leave Islam, but he made a great error, even saying that you are not disbelievers in the Qur'an. The Qur'an says that Allah stated in it: This is what the Christians are upon now; they say that Jesus is the son of Allah. This is greater than that disbelief; Allah has ruled that they are disbelievers. Yes.
Therefore, he should repent to Allah and seek forgiveness, and inform the Christian that in the Qur'an, whoever believes that Jesus is the son of Allah or the third of three is a disbeliever by the text of the Qur'an. Yes.

The questioner:
Honorable Shaykh, may Allah grant you success.

The Shaykh:
Also, even if he did not say that Allah is the third of three and that Jesus is the son of Allah, if he disbelieves in Muhammad (peace and blessings be upon him), he is a disbeliever. Yes.
