ISIS is against. that organization having rude and extremists type rules and regulation but on the other hand Islam is peaceful . Best example is 8 hegira fatah e makkah . prophet Muhammad (SAWW) give message of peace
ISIS is intent on establishing an Islamic state and quotes scripture with each attack. Although perhaps founded due to political instability in the middle east, ISIS quite clearly is an extremely religious organisation with suicide bombers intent on seeing a martyrs paradise, and using the teachings of Mohammed as inspiration for many of their horrific crimes. Islam is by no means a peaceful religion, and ISIS is simply a reflection of that glaringly obvious point.
Nothing to rebutt, I stand by my case, Islam is not peaceful. I'm sure that lots of muslims are against what ISIS do, however that does not mean the ideology is fundamentally opposed to what ISIS does.
