Hawzah News Agency – Allah SWT in the Qur’an states that:

وَلَا يَطَئُونَ مَوْطِئًا يَغِيظُ الْكُفَّارَ وَلَا يَنَالُونَ مِنْ عَدُوٍّ نَّيْلًا إِلَّا كُتِبَ لَهُم بِهِ عَمَلٌ صَالِحٌ.

“Neither tread they any tread enraging the unbelievers, nor gain any gain from any enemy, but a righteous deed is thereby written to their account.” 1

In other words, a group action that angers the unbelievers will not go unrewarded. So yes, a demonstration that angers the enemy of Islam and Muslims is a good deed.

The demonstrations and protests (especially those that are transmitted through means of satellite, television, social media and the like) that are attended with divine intentions are a form of congregational worship and a means of enjoining what is right and forbidding what is wrong and is a means of lifting the spirits of the believers and a threat to the enemy.
