6. He said: Abul Hasan ‘Ali ibn Bilal al-Mahlabi reported to me from Abu Ahmad al-Abbas ibn al-Fadhl ibn Ja’far al-Azadi al-Makki, in Egypt, who reported from ‘Ali ibn Saeed Ibn Basheer al-Razi, who reported from ‘Ali ibn Abdul Wahid, from Muhammad ibn Aban, who reported from Muhammad ibn Tamam ibn Sabiq, who reported from Amir ibn Sayyar, from Abu al-Sabah, from Abu Tamam, from Ka’b al-Habr, who said: Abdullah ibn Salaam came to the Prophet before he had embraced Islam, and said: "O Messenger of Allah! What appellation does ‘Ali have among you?" The Prophet, peace be upon him and his progeny, said: "‘Ali is al-Siddiq al-Akbar among us." Abdullah said: "I testify that there is no god but Allah and that Muhammad is His Prophet. Surely, we have read in Torah: Muhammad is the Prophet of Mercy and ‘Ali is the upholder of Proof."
