The birth of Muslim Brotherhood coincided with a state of political momentum during King Farouk's era and the British occupation to Egypt, when the group's founder threw its first seed from Ismailia province before leaving to Cairo. Both the group and then-ruling regime were heavy burden for the Egyptian people for decades. There is a relation between Muslim Brotherhood and other Islamist movements, as the mother group inside the Islamist organization as whole. It views itself as the most rational and mature among the other Islamist groups. Despite the intra differences between Muslim Brotherhood and other Islamist groups, It worked to adapt with the other groups twice; the first, when it ascended to power due to mutual need. The mother group needed their support after losing the other non-religious movements in an unjustified conflict, while the other small groups hoped to achieve their project after decades between prisons and caves. The second, when it was ousted from power, it turned to gain the support of its friends that defended the Islamist project around which the different Islamist organizations rallied. This is the main reason that prompts the Muslim Brotherhood not to condemn any of the terrorist actions committed by Ansar Bayt Al Maqdes whether before or after announcing its loyalty to the Islamic State (IS). On the contrary, the group turned to praise such actions viewing them as legal defense of the group and to achieve victory. It was not surprising for the followers and observers that Muslim Brotherhood enjoys a good relation with IS loyal groups since it was ruling the country. It was containing and supporting Ansar Bayt Al Maqdes, while the security authorities expressed their concern over such policies. Morsi was keen to draw the relations with such groups, as he opened the dialogue with their leaders through the presidential institution. The presidential officials visited those terrorist leaders in their caves in Jabal Al Halal to negotiate with and to offer concessions to them at the expense of the Egyptian state. This dialogue ended with Morsi's refusal to sign any decree to execute the death sentences issued against their militias. The formerly ruling group believed that it was able to contain the threat imposed by the extremist groups and to benefit them to achieve balance of power in the internal arena. Meanwhile, it promoted itself as the moderate current while the others are extremists. Muslim Brotherhood did not condemn any terrorist actions committed by Ansar Bayt Al Maqdes, including the attack against Daqahlia's Security Directorate on December 24, 2013 in the beginning, while it took the step later as the then-Prime Minister Hazem Al Beblawy described the group as terrorist. The group also did not condemn the killing of National Security Officer Mohamed Mabrouk authorized to collect the evidences against former President Mohamed Morsi, while it denied any relations with his assassination. The group's position reflects its satisfaction toward the terrorist operations committed in Egypt, as they serve the group's interests.
