• Every newly invented matter is an innovation, and every innovation is misguidance
• Tawḥīd: all good is from Allāh and returns to Him, even when a person helps you
• Muslims buying into the occult through popular culture
• Holding firm to the Muslim's own festivals and rites
• Knowledge is the weapon: "Know that there is none worthy of worship except Allāh"
