Is it obligatory to warn people about fabricated or weak hadiths, and is one who ignores this considered sinful? And what is the method for warning them while taking care not to spread doubts? And can a weak hadith be described as possibly false? And is the one who made a mistake obligated to clarify, or is repentance and seeking forgiveness sufficient for him? And how many times should the warning be given?

There is no error in the fatwa referenced by number: 9898. The wording of the hadith, according to most transmitters, is "the supplication of the parent against his child," whereas the wording of Ibn Majah is "the supplication of the parent for his child." The disagreement regarding authentication and weakening among hadith scholars is similar to the disagreement among jurists, and it is a permissible difference of opinion. Asserting definitively the authenticity or weakness of many hadiths is not easy. The person suffering from obsessive doubts should avoid indulging in these thoughts due to the confusion, doubt, and distress they cause, and he should cast off these thoughts from himself.
