I said: someone like him does not have his ḥadīth fall below the level of ḥasan. And Allāh knows best. Perhaps the ḥadīth refers to changing the system of selecting the caliph and making it hereditary. And Allāh knows best.

"Whoever I am his master, ʿAlī is his master. O Allāh, befriend whoever befriends him and oppose whoever opposes him." It is reported from the ḥadīth of Zayd ibn Arqam, Saʿd ibn Abī Waqqāṣ, Buraydah ibn al-Ḥuṣayb, ʿAlī ibn Abī Ṭālib, Abū Ayyūb al-Anṣārī, al-Barāʾ ibn ʿĀzib, ʿAbd Allāh ibn ʿAbbās, Anas ibn Mālik, Abū Saʿīd, and Abū Hurayrah. 1 - The ḥadīth of Zayd, and there are five chains from him: the first is from Abū al-Ṭufayl from him who said: When the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) returned from the Farewell Pilgrimage and stopped at Ghadīr Khumm, he ordered that some trees be cleared, then said: "It is as if I have been called and I have responded, and I am leaving among you two weighty things, one of which is greater than the other: the Book of Allāh and my family, the people of my house. So, see how you deal with them after me, for they will not separate until they return to me at the Pond." Then he said: "Indeed, Allāh is my master, and I am the master of every believer." Then he took ʿAlī's (raḍiya Allāhu ʿanhu) hand and said: "Whoever I am his master, this is his master. O Allāh, befriend whoever befriends him and oppose whoever opposes him." It was recorded by al-Nasāʾī in "Khaṣāʾiṣ ʿAlī" (p. 15), al-Ḥākim (3/109), Aḥmad (1/118), Ibn Abī ʿĀṣim (1365), and al-Ṭabarānī (4969-4970) from Sulaymān al-Aʿmash who said: Ḥabīb ibn Abī Thābit narrated from him, and al-Ḥākim said: "Authentic according to the criteria of al-Bukhārī and Muslim." I said: al-Dhahabī remained silent about it, and it is as he said, except that Ḥabīb was known for tadlīs and he narrated it with ʿanʿanah
