Islamic Jihad and Hamas, both offshoots of the Muslim Brotherhood, and ideological cousin to ISIS, is blaming Israel for the horrific terror attack against a Sufi mosque in Egypt.
Gaza clerics held a meeting to respond to the attacks, and Gaza terror groups are very sensitive to upsetting Egypt, since the Rafah border crossing is important to them for travel and Egypt has blamed Gaza terror groups for arming Sinai terror groups. It appears that Islamic Jihad and possibly Hamas was involved in putting this emergency meeting together to distance those Islamist terror groups from Sinai Islamist terror groups.
The main theme of their statements was that the purpose of these attacks was to '"establish chaos in the Egyptian Republic and turn it into separate entities to serve the enemies of the Islamic religion, especially the Israeli entity."
Sheikh Abdul Fattah Hajjaj, head of the Iqra Charity Association, said "this murder and terrorism that targeted Egypt raises questions about the objectives of those terrorist groups that serve only the Zionist enemy."
Sheikh Nimer Abu Aoun said on behalf of his fellow Islamist sheikhs that "We are absolved of the criminal act that targeted Egypt and Arabism and this terrorist act is forbidden in Islam" and called for "Love, cooperation, harmony and tolerance among the sons of the Arab and Islamic nation because the Islamic religion is one religion for all people." He said the attack was "a conspiracy run by the enemies of Islam against Egypt and its people and its army."
Sheikh Samih Hajjaj, the General Director of the Azhar Institutes in Palestine, said the attack was meant "to weaken the great army feared by Israel, and rid Egypt of any economic and social plans."
Keep in mind that the media in Gaza, including religious media, is filled with calls to violence and murder. But not usually against other Muslims.
A mark of maturity is the ability to take responsibility for things. ISIS, Al Qaeda and other terror groups didn't appear out of a vacuum - their founders were all members of the Muslim Brotherhood, as were the founders of Hamas and Islamic Jihad. There is no difference in their interpretations of the Koran that I am aware of. By claiming that these ISIS and ISIS-inspired attacks are really done on behalf of Israel (or, as Iran says, the US,) the Muslim world is not doing anything to actually solve the problem. On the contrary, they are trying to distance themselves from these groups - because they know that their own support for terror is not very far from that of ISIS and al-Qaeda and they do not have an ideological leg to stand on.
