Abu Umar Zadhan says: I saw Sayyiduna Ali (may Allah be pleased with him) in Rahbah, and he was beseeching the people by Allah, saying: Whoever was present with the Messenger of Allah (peace and blessings be upon him) on the day of Ghadir Khumm, when he said what he said (from your response, the meaning of his statement is understood), then thirteen men stood up and testified that they had heard the Messenger of Allah (peace and blessings be upon him) say: Whoever I am his friend, Ali is also his friend.

Saeed bin Wahb and Zaid bin Yuthai’ say: Sayyiduna Ali (may Allah be pleased with him) in Rahbah, made the people swear by Allah and said: Whoever among you heard the Messenger of Allah (peace and blessings be upon him) say this hadith on the day of Ghadir Khumm, let him stand up. So, six men from Saeed’s side and six men from Zaid’s side stood up, and all of them testified that they had heard the Messenger of Allah (peace and blessings be upon him) say regarding Sayyiduna Ali (may Allah be pleased with him) on the day of Ghadir Khumm:“Does not Allah have more right over the believers?”The companions said: Yes, indeed. He (peace and blessings be upon him) said:“O Allah! Whomever I am his friend, Ali is also his friend. O Allah! Befriend whoever befriends him, and show enmity to whoever shows enmity to him.”

Saeed and Zaid also narrate this, with these additional words: The Prophet (peace and blessings be upon him and his family) said: O Allah! Help the one who helps Ali, and forsake the one who forsakes him.

It is narrated from Saeed bin Wahb that Sayyiduna Ali (may Allah be pleased with him) invoked Allah as a witness before the people, so five or six companions stood up and testified that the Messenger of Allah (peace and blessings be upon him) had said: "Whoever I am a friend to, Ali is also his friend."

It is narrated from Saeed bin Musayyib (may Allah have mercy on him), he says: I said to Sa’d bin Malik, that is, our master Sa’d bin Abi Waqqas (may Allah be pleased with him): I want to ask you about a hadith, but I am also in awe of you. He said: Nephew! Do not do so, if you know that I have knowledge of something, then ask me and do not be afraid of me. I said: When the Messenger of Allah (peace and blessings be upon him) left our master Ali (may Allah be pleased with him) behind in Madinah on the occasion of the Battle of Tabuk, what did he say? Our master Sa’d (may Allah be pleased with him) said: When the Noble Prophet (peace and blessings be upon him) left our master Ali (may Allah be pleased with him) behind in Madinah on the occasion of the Battle of Tabuk, he (Ali) said: O Messenger of Allah! Are you leaving me behind among the children and women who stay behind? The Prophet (peace and blessings be upon him) said: Are you not pleased that your relationship to me is like that of Harun (peace be upon him) to Musa (peace be upon him)? He said: Yes, O Messenger of Allah! Upon hearing the words of the Prophet (peace and blessings be upon him), our master Ali (may Allah be pleased with him) happily and swiftly returned, as if even now I can see the dust rising from his feet. The words of the narrator Hammad are: Upon hearing this, our master Ali (may Allah be pleased with him) swiftly returned.

(Second chain) Sayyiduna Ali (may Allah be pleased with him) says that he went out with the Noble Prophet (peace and blessings be upon him), until when the Prophet (peace and blessings be upon him) reached Thaniyyah al-Wada', Sayyiduna Ali (may Allah be pleased with him) said while weeping: "You are leaving me behind among those who remain, that is, women and children." The Prophet (peace and blessings be upon him) said: "Are you not pleased that your relation to me is like that of Harun (peace be upon him) to Musa (peace be upon him), except that there is no Prophethood after me?"

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that (on the occasion of the Battle of Tabuk) when the Messenger of Allah (peace and blessings be upon him) intended to leave Sayyiduna Ali (may Allah be pleased with him) behind, Sayyiduna Ali (may Allah be pleased with him) said: If you leave me behind like this, what will people say about me? The Messenger of Allah (peace and blessings be upon him) said: Are you not pleased that your relation to me is like that of Harun (peace be upon him) to Musa (peace be upon him), except that there will be no prophet after me?

It is narrated from Musa Jahni, he says: I went to Fatimah bint Ali, my companion Abu Sahl asked her: How old are you? She said: Eighty-six years. Abu Sahl asked: What have you heard about your father (Sayyiduna Ali, may Allah be pleased with him)? She said: Sayyidah Asma bint Umais, may Allah be pleased with her, narrated that the Messenger of Allah, peace and blessings be upon him, said to Sayyiduna Ali, may Allah be pleased with him: "Your position to me is like that of Harun (Aaron) to Musa (Moses), except that there is no prophet after me."

It is narrated from Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) that on the day of Khaybar, the Messenger of Allah (peace and blessings be upon him) said:“Tomorrow I will hand over this flag to a man by whose hands Allah will grant victory. He loves Allah and His Messenger, and Allah and His Messenger love him.”The people spent the whole night wondering who among them would be given the flag. In the morning, the people came to the Messenger of Allah (peace and blessings be upon him), each hoping that he would be given the flag. The Messenger of Allah (peace and blessings be upon him) said:“Where is Ali bin Abi Talib?”The people replied:“O Messenger of Allah! His eyes are sore.”People were sent to bring him. When he was brought, the Messenger of Allah (peace and blessings be upon him) applied his saliva to his eyes and prayed for him. He was immediately cured as if he had never had any pain. Then the Prophet (peace and blessings be upon him) handed him the flag. He (Ali) said:“O Messenger of Allah! Should I fight them until they become like us (i.e., Muslims)?”The Prophet (peace and blessings be upon him) said:“Proceed calmly until you reach them. Then first invite them to Islam and inform them of the rights of Allah upon them in Islam. By Allah! If Allah guides a single man through you, it is better for you than red camels.”

It is narrated from Sayyiduna Buraidah Aslami (may Allah be pleased with him), he says: We laid siege to Khaybar, and the flag was in the hand of Sayyiduna Abu Bakr (may Allah be pleased with him). He returned and there was no victory. The next day, again the flag remained with him, and that day too he returned and victory was not achieved. On that day, people faced much hardship and difficulty. The Messenger of Allah (peace and blessings be upon him) said: Tomorrow I will hand over this flag to such a man that Allah and His Messenger love him and he loves Allah and His Messenger, and he will not return without victory. We spent the night in happiness, hoping that victory would come the next day. When morning came and the Messenger of Allah (peace and blessings be upon him) led the prayer, he stood up and called for the flag. The people remained seated in their rows. The Messenger of Allah (peace and blessings be upon him) called for Sayyiduna Ali (may Allah be pleased with him); his eyes were hurting. The Messenger of Allah (peace and blessings be upon him) applied his blessed saliva to his eyes and handed the flag to him. Victory was granted at his hands. Sayyiduna Buraidah (may Allah be pleased with him) says: Among those who raised their necks in desire to receive the flag, I was also included.
