The brutal beheading of American journalist James Foley by Islamic State has brought out a chorus of opposition from Muslims the world over.
In a recent, Indonesia, the world's most populous Muslim-majority country, condemned the actions of the Islamic militant group and claimed it is embarrassing the religion and its believers.
Indonesian President Susilo Bambang Yudhoyono stated that Muslim leaders should be united in tackling extremism.
"It is shocking. It is becoming out of control," Al Arabiya quoted Yudhoyono as saying. "We do not tolerate it, we forbid ISIS in Indonesia."
The Indonesian President also urged international leaders to work together to combat radicalisation.
"This is a new wake-up call to international leaders all over the world, including Islamic leaders," he said, adding that the actions of IS have been "humiliating" to Islam.
Indonesia is home to the world's biggest Muslim population of about 225 million, and has struggled with terrorism for years. However, the government has been able to clamp down on several terrorist recruitment centres.
The statement from the Indonesian President comes after Egypt's most influential Muslim cleric condemned the actions of Islamic state.
"An extremist and bloody group such as this poses a danger to Islam and Muslims, tarnishing its image as well as shedding blood and spreading corruption," Grand Mufti Shawqi Allam stated.
Allam's views are held in high regard as they are seen as the opinion of Al Azhar, which is one of the world's oldest seats of Muslim learning. It is respected and followed by Muslims worldwide.
The Muslim Council of Britain has also condemned IS.
"The Muslim Council of Britain condemns the actions of the so called 'Islamic State in Syria and the Levant', ISIS. Today we express once again our rebuke of this reprehensible organisation," read a statement on behalf of British Muslims.
"We are horrified at the abhorrent murder of James Foley, a reporter who initially went to the region to expose the human rights abuses of the Syrian regime. ISIS has murdered this man for no reason at all."
