What should a Muslim do when hearing the Prophet, peace and blessings be upon him, being cursed in a group chat program where he cannot respond to the abusers?

The enemies of Allah cannot harm Islam except through insults and curses. A Muslim should turn away from the ignorant so as not to expose Islam to their insults, as Allah Almighty says: "And do not insult those they invoke other than Allah, lest they insult Allah in enmity without knowledge." It is not permissible to enter their websites or engage in dialogue with them unless the Muslim is strong enough to refute them and prove the superiority of Islam, as Allah Almighty says: "And He has already sent down to you in the Book that when you hear the verses of Allah being denied and ridiculed, then do not sit with them until they enter into another conversation. Indeed, you would then be like them." Engaging in discussion with them without the ability to defend Islam leads to harming oneself and the religion. The Prophet (peace be upon him) said: "It is not befitting for a believer to humiliate himself." They asked: "How does a believer humiliate himself?" He said: "He exposes it to what it cannot bear." The arguments of the Christians are flimsy, and whoever wishes to debate should arm himself with religious knowledge and their knowledge.
