Blocking people who incite trouble on social media
Q: In a Hadith, our Nabi (SallAllahu 'Alayhi Wa Sallam) forbade it for Muslims to hate each other and we cannot boycott one another for more than 3 days.
My question is that on social media, some people are intent on bullying others. Would it be permissible to block people whose behaviour is harmful to a person, even if the opposite person is Muslim?
