Explanation of the Hadith: Whoever Introduces a Good Sunnah or a Bad Sunnah

Question:
The questioner says: Honorable Shaykh, this person asks and says: In the hadith he bears its sin until the Day of Judgment. What are the examples of this? And explain this hadith to us.

Answer:
He has its reward. This means that whoever revives a sunnah that people have abandoned and draws their attention to it through his words and actions, he has the reward of whoever acts upon it, because he revived it. As for whoever introduces a bad sunnah in Islam, such as bid'ah (religious innovations) and newly invented matters, for which Allah has not sent down any authority, in order to draw near to Allah with a form of worship for which there is no evidence from the Book or the Sunnah, he bears its sin and the sin of whoever acts upon it, and that does not diminish anything from their sins, may Allah protect us from that. So in this is the encouragement to revive the sunnahs and act upon them, and in it is the prohibition and warning against bid'ah and newly invented matters and acting upon them. Yes.
