The takfiri orientation damaged the reputation of Islam

The takfiri orientation damaged the reputation of Islam in the world and it painted an ugly picture of it. Everyone in the world saw on TV that someone is made to sit on the ground and they behead them with a sword without charging him with any crime: "Allah forbids you not - with regard to those who fight you not for your faith nor drive you out of your homes - from dealing kindly and justly with them: for Allah loves those who are just. Allah only forbids you - with regard to those who fight you for your faith, and drive you out of your homes, and support others in driving you out - from turning to them for friendship and protection. And whoever makes friends with them, these are the unjust" [The Holy Quran, 60: 8-9]. These people did the exact opposite of this. They killed Muslims and innocent non-Muslims and the pictures were broadcast all over the world. The whole world saw this. These acts were done in the name of Islam. This was the way they introduced Islam, which is known for its mercy, reason and logic and for "Allah forbids you not - with regard to those who fight you not for your faith nor drive you out of your homes - from dealing kindly and justly with them". Is there any crime greater than this? Is there any fitna which is more malevolent than this? This has been committed by the takfiri orientation.
