Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: "Soon there will be rulers over you who will abandon this much of the Sunnah. If you let it go, they will make it like this; and if you let it go, they will bring an even greater calamity."
This narration has been recorded by Imam al-Tabarani, and its narrators are thiqat (trustworthy).
