Abū al-Faraj(1) said: “This is a fabricated hadith(2), and the one accused of fabricating it is Abbād ibn Abd Allāh. Alī ibn al-Madīnī said: ‘He was a weak hadith narrator.’”
Abū al-Faraj(3) said: “(Hammād)(4) al-Azdī narrated(5) hadiths for which no one corroborated him. As for al-Minhāl, Shubah abandoned him. Abū Bakr al-Athram said(6): ‘I asked Abū Abd Allāh about Alī’s hadith, “I am Allah’s servant and the brother of the Messenger of Allah(7).” He replied, “Strike it out, for it is a denounced hadith(8).”’”
I say: Among what is narrated through Abbād from Alī are reports known with certainty to be falsely attributed to him, such as this hadith. We know that Alī(9) was far too righteous, truthful, and God-fearing to lie and utter words such as these—words that are a manifest falsehood and are necessarily known to be false. Whenever we know that something is a manifest falsehood admitting no confusion, we know that Alī did not say it, because we know that he feared Allah too much to deliberately tell such a vile lie, and that it is not the kind of matter(10)
