Dear respected Shaykh, assalamu alaikum wa rahmatullahi wa barakatuh. If a scholar who is an expert in hadith criticism like Abu Zur’ah or Abu Hatim grades a hadith to be weak without mentioning the reason, and the chain of narrators of the hadith is apparently authentic and sound, should the hadith be considered authentic if the reason for its weakness is vague? Should we regard the hadith as weak or should we desist from giving a ruling on it? مسائل في علم العلل
