What should be done when sitting in a gathering where the noble Companions are reviled?

There is no good in one who slanders the Companions of the Messenger of Allah (peace be upon him). It is not permissible for a Muslim to sit in a gathering where the sacred tenets of Islam are violated and the Companions are slandered. Rather, he must defend them and protect their honor. If he is unable to do so, he must leave the gathering and abandon its people, for Allah Almighty says: "And He has already revealed to you in the Book that when you hear the verses of Allah being denied and ridiculed, do not sit with them until they enter into another conversation. Indeed, in that case, you would be like them. Indeed, Allah will gather the hypocrites and disbelievers in Hell all together."
