Why have those who deny the noble Prophetic Sunnah become numerous?

Among the reasons for the spread of the denial of the Sunnah are ignorance, blind imitation, and the subjection of minds to matters of Sacred Law. It is obligatory to urge people to learn the Sunnah, adhere to it, and introduce them to it, while clarifying its authenticity and explaining what the innovators use as evidence from fabricated and weak hadiths.
