Anwar Sadat wasn't against the Ikhwan that's for sure he said and even wrote that he admired Sh Hassan al Banna and even collaborated with him as for Gamal Abdel Nasser again i disagree with Nationalism and Socialism but on what grounds can you declare kufr upon them it's well known that in Sadat's days the role of the Sharia became more important and Sadat was known to be a practicing Muslim now i am not blindly following individuals but i am not hasty with takfeer either and i cant remember any scholar from Al Azhar declaring takfeer on Sadat or Abdel Nasser or any scholar in the Islamic world i heard that Shaykh Kishk criticized both of them but takfeer i dont know but if you can proof me wrong go ahead.
