In the mid-1950s, Azzam joined the Muslim Brotherhood after being influenced by Shafiq Asad `Abd al-Hadi, an elderly local teacher who was a member of the Muslim Brotherhood. Recognizing Azzam's sharp mind, Shafiq Asad gave Azzam a religious education and introduced him to many of the Muslim Brotherhood's leaders in Palestine. Azzam became more interested in Islamic studies and started a study group in his village. Shafiq Asad then introduced Azzam to Muhammad `Abd ar-Rahman Khalifa, the "Muraqib `Am" (General Supervisor) of the Muslim Brotherhood in Jordan. Khalifa met with Azzam during several visits that he made to Silat al-Harithiya. During this part of his life, Azzam began reading the works of Hasan al-Banna and other Muslim Brotherhood writings.
