It is narrated from Abu Tahiya that when Ibn Muljam struck Sayyiduna Ali, may Allah be pleased with him, he said: Treat him in the same manner as the Messenger of Allah, peace and blessings be upon him, treated the man who intended to kill him. The Messenger of Allah, peace and blessings be upon him, said: Kill him and then burn him.

It is narrated from Abdullah bin Saba, he says: I heard Sayyiduna Ali (may Allah be pleased with him) saying: This beard of mine will be stained with the blood of my head, and the most wretched man is waiting to treat me in such a manner. The people said: O Commander of the Faithful! Tell us about him so that we may not leave any trace even of his offspring. Sayyiduna Ali (may Allah be pleased with him) said: If I do so, you will kill someone other than my actual killer. The people said: Well then, appoint someone as a caliph over us. He refused this as well and said: I will leave you just as the Messenger of Allah (peace and blessings be upon him) left you, that is, he (peace and blessings be upon him) did not appoint anyone as a caliph either. The people said: What will you say when you go to your Lord? He said: I will say: O Allah! As long as You willed, You kept me among them, then You called me to Yourself, and after me, You were among them; if You will, You may reform them, and if You will, You may cause discord among them.

It is narrated from Hubayrah, he says: Sayyiduna Hasan bin Ali (peace be upon him) delivered a sermon to us and said: Yesterday, a man departed from you who, in terms of knowledge, was not surpassed by anyone among the earlier people, nor will anyone among the later ones attain his rank. Whenever the Messenger of Allah (peace and blessings be upon him) sent him forth with a flag, Jibreel (peace be upon him) would be on his right side and Mikaeel (peace be upon him) on his left side, and he would not return without achieving victory.

(Second chain) These additional words are present in it: Sayyiduna Ali (may Allah be pleased with him) did not leave behind gold or silver; there were only seven hundred dirhams, which he had set aside for a servant for his family.

It is narrated from Zuhair bin Aqmar that after the martyrdom of Sayyiduna Ali (may Allah be pleased with him), one day Sayyiduna Hasan bin Ali (may Allah be pleased with him) was delivering a sermon when a man from Banu Asad stood up and said: I have seen that the Messenger of Allah (peace and blessings be upon him) had seated him in his lap and the Messenger of Allah (peace and blessings be upon him) said: Whoever loves me should also love him. Those who are present here should convey this message to those who are not present. If it were not for this emphasis from the Messenger of Allah (peace and blessings be upon him), I would not have narrated this hadith to you.

It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) was leading the people in prayer, and Sayyiduna Hasan bin Ali (may Allah be pleased with him) would climb onto the back of the Prophet (peace and blessings be upon him) while jumping. He did this several times. In one narration, it is mentioned that the Messenger of Allah (peace and blessings be upon him) would gently stand up so that he would not fall. Seeing this scene, the Companions (may Allah be pleased with them) said: By Allah! The way you treat him, you do not treat anyone else like that. The Prophet (peace and blessings be upon him) said: This son of mine is a leader; Allah Almighty will bring reconciliation between two great groups of Muslims through him. Hasan al-Basri said: By Allah, by Allah, not even the amount of blood that fills a vial was shed during his caliphate.

It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him), he says: I saw the Messenger of Allah (peace and blessings be upon him) seated on the pulpit and Sayyiduna Hasan (peace be upon him) was with him. The Prophet would look once towards the people and once at him, and would say: "This son of mine is a leader, and it is hoped that Allah, the Blessed and Exalted, will bring reconciliation between two groups of Muslims through him."

(Second chain) It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him), he says: One day the Messenger of Allah (peace and blessings be upon him and his family) was delivering a sermon when Sayyiduna Hasan bin Ali (may Allah be pleased with him) came. He came and went up to you on the pulpit. The Noble Prophet (peace and blessings be upon him and his family) embraced him to his chest and passed his hand over his head and said: This son of mine is a leader, and it is hoped that through him Allah Almighty will reconcile two great groups of Muslims.

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him and his family, said regarding Sayyiduna Hasan, may Allah be pleased with him: O Allah! I love him, so You also love him, and love the one who loves him.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he says: I was with the Noble Prophet (peace and blessings be upon him) in a market of Madinah. When he returned, I also returned with him. The Prophet (peace and blessings be upon him) went towards the house of Sayyidah Fatimah (may Allah be pleased with her) and, calling Sayyiduna Hasan (may Allah be pleased with him), the Prophet (peace and blessings be upon him) said three times: O child! O little one! O child! No one responded to the Prophet (peace and blessings be upon him), so he returned, and I also returned with him. Then the Prophet (peace and blessings be upon him) went and sat in the house of Sayyidah Aishah (may Allah be pleased with her). Meanwhile, Sayyiduna Hasan bin Ali (may Allah be pleased with him) also arrived. Sayyiduna Abu Hurairah (may Allah be pleased with him) says: I think his mother had held him back to put something like a necklace around his neck. When he came, the Prophet (peace and blessings be upon him) embraced him, and he clung to the Prophet’s (peace and blessings be upon him) neck. At that moment, the Prophet (peace and blessings be upon him) said three times: O Allah! I love him, so You love him too, and love the one who loves him.
