What is the ruling of demonstrations in response to those who insult the Prophet, peace be upon him?

Brothers and sisters, this is not new. At the time of the Prophet, peace be upon him, they used to call him a magician, liar, soothsayer, poet, etc., and the prophet, peace be upon him, would be patient. He wouldn’t grow impatient. Allah commanded him to be patient; “And be patient (O Muhammad) with what they say, and keep away from them in a good way” (73:10). The Prophet, peace be upon him, would hear (the insults) but keep patient in fulfilment of Allah’s, may He be glorified, order: “Indeed, We know that your breast is straitened at what they say. So glorify the praises of your Lord and be of those who prostrate themselves (to Him). And worship your Lord until there comes unto you the certainty (i.e. death)”(15:97-99). He would be patient and prevent his companions from taking revenge. He would prevent his companions from taking revenge when he was in Mecca. He would prevent his companions because if they had taken revenge on polytheists, Islam would have been demolished in Mecca; Da’wah “the call to Islam” would have been nipped in the bud. But once he migrated and found the Ansar “supporters in Madina,” Allah commanded him to fight legitimately against disbelievers. This, however, does not apply to demonstrations, vandalism, and the killing of innocents and those who are promised immunity and protected citizens. This is betrayal and unlawful. It is unlawful to kill innocents, even if they are disbelievers; it is unlawful. “And let not the hatred of some people in (once) stopping you from Al-Masjid-Al-Harâm (at Makkah) lead you to transgression (and hostility on your part)” (5:2). It is unlawful to assault innocents; "And no bearer of burdens shall bear the burden of another" (6:164).
