Ibn Ishaq states that Sayyiduna Ammar bin Yasir, his father and his mother were a wholly Muslim household. Banu Makhzum used to inflict severe torment on them (as punishment for accepting Islam), so the Messenger of Allah (peace and blessings be upon him) said: "O family of Yasir! Be patient, for Paradise is what you have been promised." The narrator said: The name of the mother of Sayyiduna Ammar bin Yasir was Sumayyah bint Salm bin Lakhm.

It is narrated from Imam Muhammad al-Baqir (Muhammad bin Ali) that Sayyiduna Ali (may Allah be pleased with him) addressed Sayyiduna Ammar bin Yasir (may Allah be pleased with him), saying: "O Abu al-Yaqzan!"

It is narrated from Abu Ka'b al-Harithi that he came to Sayyiduna Uthman (may Allah be pleased with him). Meanwhile a tall man came who was bald at the front of his head, with a few hairs remaining there. I asked: Who is this? The people said: This is Ammar bin Yasir (may Allah be pleased with him).

It is narrated from Abdullah bin Salimah: On the day of Siffin I saw Sayyiduna Ammar bin Yasir (may Allah be pleased with him). He was a tall man of wheat-brown complexion, and in his hand was a short spear (harbah).

Kulayb bin Manfa'ah narrates from his father: I saw Sayyiduna Ammar bin Yasir (may Allah be pleased with him) at "al-Kunasah," a place in Kufah. He was of dark complexion with curly hair, and at that time he was reciting this verse: "And among His signs is that He created you from dust; then, behold, you are human beings spreading (across the earth)" [Surah al-Rum: 20] .

It is narrated from Abdullah bin Salimah: On the day of Siffin I saw Sayyiduna Ammar bin Yasir (may Allah be pleased with him). He was an old, tall man; he was holding a spear in his hand, and his hand was trembling (because of old age). He said: "By the One in whose Hand is my soul! I have fought with this spear in the company of the Messenger of Allah (peace and blessings be upon him) three times, and this is the fourth time." Then he said: "By the One in whose Hand is my soul! Even if these enemies were to beat us until they drove us as far as the palm branches of Hajar (that is, an extremely distant place), I would still be certain that I am upon the truth and they are upon falsehood."

It is narrated from Urwah that in the list of the allies of Banu Makhzum who took part in the Battle of Badr, Sayyiduna Ammar bin Yasir (may Allah be pleased with him) was (also) included.
