Did Ibn Sa'd say in "Al-Tabaqat" about Al-Harith Al-A'war, "weak in his Hadith" or "weak in his opinion"? And what is Al-Harith Al-A'war's rank in Hadith?

Al-Harith ibn Abdullah al-A'war is considered weak in hadith by the majority of hadith scholars. Al-Sha'bi even accused him of lying, but some scholars interpreted this accusation as relating to his opinion and beliefs, not to his intentional fabrication of hadith. Al-Hafiz Ibn Hajar, in "Al-Tahdhib," quoted Ibn Sa'd as saying that Al-Harith held a bad opinion and was weak in his narration. It is likely that what appeared in "Al-Tahdhib" was a textual corruption, and the correct wording, as found in Ibn Sa'd's "Al-Tabaqat," is: "weak in his narration," not "in his opinion."
