Collecting a hadith about following a bad sunnah with a verse about Allah changing the sunnah of these people

Question : How do we reconcile the hadith of the Messenger (peace and blessings be upon him), “Whoever introduces a bad practice in Islam will bear the sin of whoever follows it until the Day of Resurrection,” with the saying of Allah the Exalted, “So whoever worships… the practice of these people”?

Answer : Yes. There is no problem. If he repents with a sincere repentance, Allah will forgive him, and him and the effects of his innovation. But as I told you and as you heard, he must announce his return from this innovation to the extent of his ability, and not be careless. If he has started, his conscience is bound, and the followers are required to return to the truth when their leader returns.
