كنت جالسا في المسجد أنا ورجلين معي، فنلنا من علي. فأقبل رسول الله صلى الله عليه وسلم غضبان يعرف في وجهه الغضب، فتعوذت بالله من غضبه. فقال: ما لكم وما لي؟ من آذى عليا فقد آذاني.
I was seated in the masjid with two other men. We spoke ill of ‘Ali. The Messenger of Allah salla Llahu ‘alayhi wa sallam approached in an angry state; the anger could be seen on his face. I sought refuge with Allah from his anger. He said, “What is with you and me? Whoever harms ‘Ali harms me, too.”
This hadith has been transmitted by ‘Amr ibn Shas, Sa’d ibn Abi Waqqas, Jabir, ibn ‘Abbas radiya Llahu ‘anhum.
Abu Ya’la and al Bazzar narrate the version of Sa’d ibn Abi Waqqas — from Qanan ibn ‘Abdullah al Nahmi — Mus’ab ibn Sa’d ibn Abi Waqqas narrated to us — from his father who said… (the hadith).
There is a difference of opinion regarding the transmitter Qanan. He is possibly Hassan al hadith (fair in hadith). This hadith of ‘Amr ibn Shas bolsters his rank. And Allah knows best.
Al Albani authenticated the hadith with the wording, “Whoever harms ‘Ali harms me, too.”
The remaining versions of the hadith have been mentioned in the original work, none of which are authentic.
