I asked Aba Abdillah عليه السلام about the Halal and the Haram so he said: the Halal of Muhammad is Halal forever unto the day of judgment and his Haram is Haram forever unto the day of judgment, there will be nothing other than it and nothing apart from it will come, and he said: Ali عليه السلام said: no one has innovated a Bid’a except that he has abandoned a Sunnah(by doing so).
