It is narrated from Khaythamah bin Abi Sabrah al-Ju'fi that he said: I came to Madinah and asked Allah to grant me a righteous companion to sit with, and Allah made Sayyiduna Abu Hurayrah (may Allah be pleased with him) available to me. I sat with him and said: I asked Allah for a righteous companion, and He brought me to you. He asked me: Where are you from? I said: From the land of Kufah; I have come seeking knowledge and goodness. He said: "Are there not among you Sayyiduna Sa'd bin Malik (Sa'd bin Abi Waqqas), whose supplication is answered; and Abdullah bin Mas'ud, who looked after the ablution water and the sandals of the Messenger of Allah (peace and blessings be upon him); and Hudhayfah bin al-Yaman, the keeper of the secrets of the Messenger of Allah (peace and blessings be upon him); and Ammar bin Yasir, to whom Allah granted protection from Satan upon the tongue of His Prophet (peace and blessings be upon him); and Salman (al-Farisi), the scholar of the two Books?" Qatadah said: The two Books mean the Injil (Gospel) and the Qur'an (al-Furqan). The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Ammar is filled with faith (in every fibre of his being and) down to the joints of his bones." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), if Muhammad bin Abi Ya'qub preserved it (accurately) from Abd al-Rahman bin Mahdi.

A similar narration is reported from another Companion of the Prophet (peace and blessings be upon him), that he (peace and blessings be upon him) said: "Ammar is filled with faith (in every fibre of his being and) down to the joints of his bones."

Muhammad bin Ali Ibn al-Hanafiyyah narrates from Sayyiduna Ammar bin Yasir (may Allah be pleased with him) that he came to the Messenger of Allah (peace and blessings be upon him) while he (peace and blessings be upon him) was suffering from a severe fever. The Messenger of Allah (peace and blessings be upon him) said to him: "Shall I not teach you the supplication that Jibril (peace be upon him) taught me for ruqyah?" I said: Certainly, O Messenger of Allah! So he (peace and blessings be upon him) taught him this supplication: 'Bismillahi arqika, wallahu yashfika, min kulli da'in yu'dhika. Khudhha falta-hnika' (In the name of Allah I perform ruqyah over you, and Allah will cure you of every illness that harms you. Take it, and may it be pleasant (and a means of healing) for you). This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Ammar bin Yasir (may Allah be pleased with him) that he said: I saw the Prophet (peace and blessings be upon him) (in such a state) that there was no one with him (in the early days of Islam) except five slaves, two women and Sayyiduna Abu Bakr (may Allah be pleased with them). This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim).

It is narrated from Abu Wa'il that Sayyiduna Ammar bin Yasir (may Allah be pleased with him) delivered a sermon to us that was extremely eloquent and brief. We said: O Abu al-Yaqzan! You have spoken very comprehensively and briefly. He said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Indeed, the lengthiness of a man's prayer and the brevity of his sermon are a sign of his understanding (fiqh). So lengthen the prayer and keep the sermon short." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it with this wording!

It is narrated from Amr bin Ghalib that a man spoke disparagingly of the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), in the presence of Sayyiduna Ali (may Allah be pleased with him). Sayyiduna Ammar bin Yasir (may Allah be pleased with him) said to him: "Be quiet, you disgraced and rejected one! Do you harm the beloved of the Messenger of Allah (peace and blessings be upon him)?!" This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), and they did not record it.

Masruq narrates from Sayyidah Aishah (may Allah be pleased with her) that she said: "Look to Ammar bin Yasir (that is, follow him), for he will die upon the natural religion (fitrah), unless some slip overtakes him due to old age." The chain of this hadith is sahih (authentic).

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: "I do not know of anyone who went out (to the field) during the trial (fitnah, the fighting) seeking by it only the pleasure of Allah Almighty and the Abode of the Hereafter, except Ammar bin Yasir (may Allah be pleased with him)." The chain of this hadith is sahih (authentic).

It is narrated from Abu Abd al-Rahman al-Sulami that he said: We were present at Siffin with Sayyiduna Ali (may Allah be pleased with him), and we had appointed two men to guard his horse. Whenever there was any lapse of attention on the enemy's side, he (may Allah be pleased with him) would charge at them and would not return until his sword was dyed with blood. He (may Allah be pleased with him) would say: "Excuse me, for by Allah, I did not come back until my sword refused to serve me (that is, it became blunt)." The narrator said: I saw Sayyiduna Ammar and Hashim bin Utbah (may Allah be pleased with them both) running between the two ranks. Ammar said: O Hashim! By Allah, his (the enemy's) affair will surely be overturned and his army will surely be forsaken. Then he said: "O Hashim! Paradise lies beneath the shade of the shields. The houris have adorned themselves today. Today we shall meet our beloved ones, Muhammad (peace and blessings be upon him) and his party." Then he said: "O Hashim! You are one-eyed, and there is no good in a one-eyed man who does not plunge into the thick of battle." The narrator said: So Hashim waved his banner and recited these verses: "This one-eyed man seeks a place (in Paradise) for his family; he has endured the bitterness of life until he has grown weary of it; now he must either gather the spoils or be martyred." The narrator said: Then he went off towards one of the valleys of Siffin. Abu Abd al-Rahman said: I saw the Companions of Muhammad (peace and blessings be upon him) following Ammar as though he were a banner and a signpost for them.
