It is narrated from Sayyiduna Buraydah al-Aslami (may Allah be pleased with him) that he said: I took part in the campaign to Yemen with Sayyiduna Ali (may Allah be pleased with him), and I sensed (as I thought) some harshness from him. Then, when I came into the presence of the Messenger of Allah (peace and blessings be upon him), I mentioned Sayyiduna Ali (may Allah be pleased with him) and made some complaint about him, whereupon I saw the colour of the blessed face of the Messenger of Allah (peace and blessings be upon him) change. He (peace and blessings be upon him) said: "O Buraydah! Do I not have a greater claim (priority) over the believers than they have over themselves?" I said: Certainly, O Messenger of Allah! He (peace and blessings be upon him) said: "Whoever I am the mawla of, Ali is his mawla." And after that the narrator mentioned the complete hadith. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.
