It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that people complained about Sayyiduna Ali (may Allah be pleased with him), so the Messenger of Allah (peace and blessings be upon him) stood up to deliver a sermon and said: O people! Do not complain about Ali. He is very strict regarding Allah's essence or in the way of Allah Almighty.

Sayyiduna Amr ibn Shas Aslami, may Allah be pleased with him, who was among the Companions of Hudaybiyyah, narrates: He says, I went towards Yemen in the company of Sayyiduna Ali, may Allah be pleased with him. During the journey, he was somewhat harsh with me, which caused me great discomfort in my heart. When I returned, I openly complained about him in the mosque. This matter reached the Messenger of Allah, peace and blessings be upon him. One day, I entered the mosque in the morning, and the Messenger of Allah, peace and blessings be upon him, was sitting with his Companions. When he saw me, he fixed his gaze upon me. Then, when I sat down, he, peace and blessings be upon him, said: O Amr! By Allah! You have caused me pain. I said: O Messenger of Allah! I seek refuge with Allah from causing you any harm. He, peace and blessings be upon him, said: Yes, whoever has hurt Ali has in fact caused me pain.

Sayyiduna Yahya bin Adam Sululi, may Allah be pleased with him, who was present at the occasion of the Farewell Pilgrimage, narrates that the Messenger of Allah, peace and blessings be upon him, said: "Ali is from me and I am from Ali. On my behalf, either I will fulfill (the obligation) myself, or Ali will fulfill it." The wording of Ibn Abi Bakir's narration is: "I will pay my debt myself or Ali will pay it on my behalf."

It is narrated from Sayyida Umm Salama (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him and his family) said to our master Ali (may Allah be pleased with him): No believer can harbor enmity towards you, and no hypocrite can love you.

Abu Abdullah Jadali says: I went to the service of Sayyida Umm Salama (may Allah be pleased with her). She said to me: Is it true that the Messenger of Allah (peace and blessings be upon him) is being spoken ill of among you? I said: I seek refuge with Allah, or I said: Glory be to Allah! How astonishing, or I said some similar words, (how could it be that the Messenger of Allah, peace and blessings be upon him, is spoken ill of). She said: I heard the Messenger of Allah (peace and blessings be upon him) say: Whoever speaks ill of Ali has certainly spoken ill of me.

It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: By Allah! Among the things that the Messenger of Allah (peace and blessings be upon him) told me specifically was this: Only a hypocrite will harbor enmity towards me, and only a believer will love me.

It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: When this verse {وَأَنْذِرْ عَشِیرَتَکَ الْأَقْرَبِینَ} … "And warn your nearest relatives" was revealed, the Noble Prophet (peace and blessings be upon him) gathered the people of his family, thirty people gathered, they ate and drank, after that the Prophet (peace and blessings be upon him) said to them: Who among you will guarantee the repayment of my debts and the fulfillment of my promises, as a result of which he will be with me in Paradise and will be my successor among my family? One man replied: O Messenger of Allah! You are like an ocean, who can fulfill these responsibilities? Then the Prophet (peace and blessings be upon him) said this to someone else as well. Then when the Prophet (peace and blessings be upon him) presented this matter to his household, Sayyiduna Ali (may Allah be pleased with him) said: Yes, I guarantee it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that after Sayyidah Khadijah (may Allah be pleased with her), the first person to perform prayer with the Noble Prophet (peace and blessings be upon him and his family), or after her, the first to accept Islam, was Sayyiduna Ali (may Allah be pleased with him).

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him), he says: In the time of the Noble Prophet (peace and blessings be upon him), we used to say that the Messenger of Allah (peace and blessings be upon him) is the most virtuous of all people, after him is Sayyiduna Abu Bakr (may Allah be pleased with him), and after him is Sayyiduna Umar (may Allah be pleased with him). And Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) was granted three such distinctions that if I had received even one of them, it would have been dearer to me than red camels: the Messenger of Allah (peace and blessings be upon him) married his daughter to him, his offspring came from him, and the Noble Prophet (peace and blessings be upon him) ordered all the doors opening into the mosque to be closed except his door, and on the day of Khaybar, the Prophet (peace and blessings be upon him) granted him the flag.

It is narrated from Abdullah bin Raqeem Kanani, he says: During the days of the Battle of Jamal, we set out towards Madinah Munawwarah and met Sayyiduna Sa’d bin Malik (may Allah be pleased with him).
