Fareed Abdul-Khaliq (one of the former Murshids of Ikhwaan) said in (الإخوان المسلمون في ميزان الحق) Ikhwan ul-Muslimoon Fee Mizanil-Haqq, (p.115):
ألمعنا فيما سبق إلى أن نشأة فكر التكفير بدأت بين شباب بعض الإخوان في سجن القناطر في أواخر الخمسينات وأوائل الستينات، وأنهم تأثروا بكفر الشهيد سيد قطب وكتاباته، وأخذوا منها أن المجتمع في جاهلية، وأنه قد كفر حكامه الذين تنكروا لحاكمية الله بعدم الحكم بما أنزل الله، ومحكوميه إذا رضوا بذلك
We have pointed out in what has preceded that the spread of the ideology of Takfir occurred amongst the youth of the Ikhwaan who were imprisoned in the late fifties and early sixties, and that they were influenced by the ideology of the Shaheed Sayyid Qutb and his writings. They derived from these writings that the society had fallen into Jahiliyyah (of kufr), and that he had performed Takfir of the rulers who had rejected the Hakimiyyah of Allaah by not ruling by what Allaah has revealed, and also Takfir of those ruled over (i.e. civilians), when they became satisfied with this.
