Warning Against Religious Innovations and New Matters in the Religion

Question:
May Allah reward you and bless you. Honorable Shaykh, a questioner says: Is there a word of guidance warning against new matters in the religion, and the effect of that on the Muslim's religion, given that the paths of shirk (associating partners with Allah) have multiplied in our present time?

Answer:
Allah (Exalted and Majestic is He) said: and the ones in authority among you, and He said: So acts of worship are based on divine legislation; nothing is done from them except with evidence from the Book and the Sunnah. We do not perform an act of worship that has no evidence from the Book and the Sunnah. We say, "This is the practice of so-and-so," or "This is the practice of such-and-such a place," or "This is the practice of such-and-such a group," unless there is evidence for it, in which case it is rejected. He said:
All bid'ah (religious innovations) are rejected and are not accepted by Allah (Glorified and Exalted is He). It is obligatory for Muslims to adhere to the Book and the Sunnah in their actions and acts of worship. This is the obligation of every Muslim man and woman. Yes.
