At least 33,000 people have been executed by ISIS in the name of Religion, which doesn’t preach extremism. The majority of the people executed by ISIS are Muslims. Anyone who refuses to accept “Their teachings” they execute that person right away. Islam never taught brutality and extremism.

Qur’an, 5:32
We have been warned several times by our last prophet Muhammad (PBUH), about the existence of these extremist groups in near future, which doesn’t have any affiliation with Islam but they will call themselves Muslims.
In Sahih Muslim 1067, Book 12, Hadith 206, its written that Muhammad Prophet (PBUH) said,
“There will be a group of people will arise after me, who would recite Quran, but Quran will not be in their heart. These people would among the worst creatures alive on this earth.“
In another Hadith, Sahih Muslim 1066, Book 12, Hadith 199, He (PBUH) said,
“These people would arise at the end of an age when there were Immature in thought and young in age. But they will talk as they are the best among all the mankind. They will recite Qur’an, but they will not understand it. If you meet them (Extremist People), kill them! and ALLAH will give you the best reward for killing such men.”
