Is it a sin to bully a non-Muslim? I totally know that the answer is an absolute no but this muslim guy who is more like a lousy hypocrite and he bullies athiest, hindus, jews and whatnot; I keep telling him that what he is doing is not right and in my heart I know that you should respect all religions because the last prophet peace be upon him was bullied by non muslims but was still nice to them anyway. I want a professional to confirm my statements.
In the Quran, Surah Isra, 17:70, Allah (swt) said, “And indeed we honored the children of Adam…” If Allah honored all human beings and we disrespect them we are falling into error and oppression.
Also, Surat al Fatihah says, “Praise be to Allah Lord of All the Worlds.” This is inclusive of all human beings. If you harm or bully, you are coming against their Lord and Protector.
In Surat al-Anbiya, 21: 107, “And We did not send you (O Muhammad) except as a Mercy to All of the Worlds.” If we follow the footsteps of the Prophet (saws), then we have to exemplify Mercy to All human beings, we should not contradict mercy to all creatures by speech or behavior.
