It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever obeys me has obeyed Allah, and whoever disobeys me has disobeyed Allah; and whoever obeys Ali has obeyed me, and whoever disobeys Ali has disobeyed me." This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs did not record it.

It is narrated from Ubaydullah bin Abi Mulaykah that a man from the people of Sham came and reviled Sayyiduna Ali (may Allah be pleased with him) in the presence of Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both). Ibn Abbas (may Allah be pleased with them both) pelted him with pebbles and said: "O enemy of Allah! You have hurt the Messenger of Allah (peace and blessings be upon him). (Allah Almighty says:) 'Indeed, those who hurt Allah and His Messenger, Allah has cursed them in this world and the Hereafter and has prepared for them a humiliating punishment' [Surah al-Ahzab: 57] . Had the Messenger of Allah (peace and blessings be upon him) been (alive), you would certainly have hurt him." This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs did not record it.

It is narrated from Sayyiduna Amr bin Shas al-Aslami (may Allah be pleased with him), who was one of the people of al-Hudaybiyah, that he said: We set out for Yemen with Sayyiduna Ali (may Allah be pleased with him), and during that journey he treated me with some coldness, so much so that I felt (some resentment) in my heart. When I returned, I began complaining about him in the mosque, until this reached the Messenger of Allah (peace and blessings be upon him). He says: One morning I entered the mosque while the Messenger of Allah (peace and blessings be upon him) was sitting among his Companions. When he (peace and blessings be upon him) saw me, he fixed his gaze on me and stared at me. When I sat down, he (peace and blessings be upon him) said: "O Amr! By Allah, you have hurt me." I said: I seek refuge with Allah from hurting you, O Messenger of Allah! He (peace and blessings be upon him) said: "Yes indeed; whoever hurts Ali has hurt me." This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs did not record it.
