Sayyiduna Buraydah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) sent Sayyiduna Ali (may Allah be pleased with him) as governor over Yemen and dispatched Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) to the mountain region, and said: "If you two come together, then Ali will be in command over the people." Then the two armies met, and they obtained spoils such as they had never obtained before, and Sayyiduna Ali (may Allah be pleased with him) took a slave-girl from the khumus (the one-fifth share). Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) called Sayyiduna Buraydah (may Allah be pleased with him) and said: "Seize this opportunity and inform the Prophet (peace and blessings be upon him) of what Ali has done." So I came to Madinah and entered the mosque; at that time the Messenger of Allah (peace and blessings be upon him) was in his house, and some of his Companions (may Allah be pleased with them) were at his door. They asked: "Buraydah, what is the news?" I said: "Good; Allah has granted victory to the Muslims." They asked: "What has brought you?" He said: "A slave-girl whom Ali has taken from the khumus; I have come to inform the Prophet (peace and blessings be upon him)." The Companions said: "Do tell him, for this will lower him in the eyes of the Messenger of Allah (peace and blessings be upon him)." the Messenger of Allah (peace and blessings be upon him) was hearing this conversation, so he (peace and blessings be upon him) came out in anger and said: "What is the matter with people that they belittle Ali? Whoever belittles Ali has belittled me, and whoever separates from Ali has separated from me. Indeed, Ali is from me and I am from him; he was created from my clay, and I was created from the clay of Ibrahim (peace be upon him), and I am superior to Ibrahim. 'Offspring, some of them from others; and Allah is All-Hearing, All-Knowing.'" And he (peace and blessings be upon him) said: "O Buraydah, do you not know that Ali's right is far greater than the slave-girl he took, and that he is your guardian (wali) after me?" I said: "O Messenger of Allah, by (the right of) companionship, I ask you to stretch out your hand so that I may pledge allegiance to you upon Islam anew." He says: "I did not leave him until I had pledged allegiance to him upon Islam."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Abu Ishaq only with this chain, and Husayn al-Ashqar is alone in narrating it."
