What is the advice for one who has joined a misguided sect?

Question:
The questioner says: I have a companion who joined some of the misguided sects, and that is because they possess some good. Is there any advice?

Answer:
Yes, the advice is that he should return to the people of truth, and to what the Messenger of Allah (peace and blessings be upon him), his Companions, the Rightly Guided Caliphs, and Your Excellency, the people of the Sunnah and the community, were upon. We advise him to return to the truth. Returning to the truth is a virtue, and returning to the truth is better than persisting in falsehood. It is not sufficient that some of the sects have good; this is not enough. It is necessary that their doctrine be pure, following the methodology of the Salaf. As for them having a deviation from the methodology of the Salaf, this is not acceptable, even if they have some good. It is among the Sunnah of Allah that some matters contain some good, but one looks to see whether the good is predominant or the evil is predominant. If the evil is predominant, then this good does not make this doctrine acceptable; the one whose evil is more than his good is not acceptable. But if the good is predominant, then it is acceptable. Yes.
