What is the ruling on attributing words to the Messenger of Allah, such as when one of them says, "I am telling you about Pepsi"?

The questioner:
One of the secularists sat in one of the gatherings and said, "I am telling you about Pepsi." The people present said, "Yes." He said, "My father told me, from his father, from Abu Hurayrah, that the Prophet (peace and blessings be upon him) said, 'Whoever drinks Pepsi is not one of us.'" The question is: Is there a disbeliever who says this or not? And what is obligatory for me regarding him, even though I know that he hates everything that is attributed to Islam?

The Shaykh:
The apparent nature of this is that he is mocking; its apparent nature is mocking Islam, mocking the Companions. This is its apparent nature. If this is established against him, it should be reported to the authorities. This is what should be done after that; rather, it is obligatory that it be reported. This is his action: it is mockery and frivolity regarding the Sunnah of the Messenger of Allah (peace and blessings be upon him) and regarding the Companions. We ask Allah for well-being and safety.

The questioner:
He descended deliberately upon the Messenger. He descended.

The Shaykh:
In the case of the deliberate one, a sane person would say, "Well," but some of the scholars of knowledge consider him a disbeliever.

The questioner:
Yes.

The Shaykh:
And Abu Muhammad al-Juwayni and the group say that whoever lies about the Prophet is a disbeliever, even if he is a Muslim. But this is apparently frivolity, not lying. We ask Allah for well-being.
