Muslim Brotherhood (MB) was established in the 30s of the 20th century, based on religious principles, but after 87 years from that date, some of the Brotherhood's members turned their efforts on business, investing their money in all fields. Despite the few statistics about the Brothers' wealth or the volume of their commercial activities, MBs are well known for owning multiple multi-economic corporations within the Egyptian economy. Following the ouster of president Mohamed Morsi in July 2013 after mass popular uprising against his rule, things have changed. The transitional government labeled the MB as a terrorist organization, prosecuting most of its leaders and members, and banning all the group's activities in Egypt. Former interior minister Mohamed Ibrahim announced in November 2013 that MBs use their economic activities to fund terrorist attacks against civil and security targets, among claims that MBs receive foreign funds to help Jihadists in Sinai Peninsula. In September 2013, authorities formed an inventory commission to manage the MB members' assets, revealing that MB activities were ramified. MB businessmen invested in building hospitals, schools, tourism companies, NGOs, charity, Islamic relief associations, large markets and other projects, but their most important investment was Islamic schools. The group used those schools to spread its thoughts among students and children, to produce generations that believe in their dogma and loyal to the Brotherhood. An MB source said before that MBs own and manage about 61 schools across the country, with claims that the real number may exceed 120 schools. Former minister of education Mahmoud Abul Nasr revealed in September 2013 that MB schools replaced the Egyptian national anthem with a Jihadi one. In May 2015, the MB inventory commission announced that the famous Al Ahly football player Mohamed Abu Treika was a partner in an MB Tourism company called (Ashab), freezing his shares in the company. The case raised wide controversy within the Egyptian community and the fans of Al Ahly club. It seems clear that Muslim Brotherhood with its associations, schools, hospitals and large trade volume, has managed to infiltrate into the Egyptian society and economy. Many Egyptian political analysts believe that MB economic projects represent a real threat on the society, since they use them to inculcate the group's extreme doctrine within it.
