Mentioning a rule established by Shaykh al-Islam Ibn Taymiyyah regarding innovations.

The Shaykh : And among the best things transmitted on this occasion is the statement of Shaykh al-Islam Ibn Taymiyyah (may Allah have mercy on him), for he established a very important rule derived from those hadiths and other texts indicating that the original ruling for things is permissibility. This is a rule of the principles of jurisprudence. He said (may Allah have mercy on him): "The original ruling in religion is prohibition except for a text, and the original ruling in worldly matters is permissibility except for a text." He means that every innovation in religion is forbidden, while an innovation in worldly matters is permissible, unless a text is known, as we mentioned. Then, it should be noted that his statement (peace and blessings be upon him): means that every act of worship that occurred after the Prophet (peace and blessings be upon him) is misguidance, even if many people think it is good.
