Mention of Abu Ubaydah's front teeth being lost while pulling the rings of the helmet from the cheeks of the Prophet (peace and blessings be upon him)

It is narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) that he said: When the people scattered away from the Messenger of Allah (peace and blessings be upon him) on the day of Uhud, I moved to one side and said (to myself): I will defend myself; either I will be martyred, or I will escape and join the Messenger of Allah (peace and blessings be upon him). While I was in this state, suddenly I saw a man who had covered his face; I did not know who he was. Meanwhile the polytheists charged, until I thought they would overpower that man, but he filled his fist with pebbles and threw them in their faces, which forced them to turn their backs and flee on their heels towards the mountain. He did this several times. I did not know who he was, and between him and me was al-Miqdad bin al-Aswad (may Allah be pleased with him). I was just about to ask al-Miqdad about him when al-Miqdad (may Allah be pleased with him) said: O Sa'd! This is the Messenger of Allah (peace and blessings be upon him) calling you. I asked: Where is he? So al-Miqdad (may Allah be pleased with him) pointed towards him. I stood up, and I felt as though no harm had touched me at all. The Messenger of Allah (peace and blessings be upon him) said: "O Sa'd! Where were you today?" I said: Right where you saw me, O Messenger of Allah! Then he (peace and blessings be upon him) seated me in front of him, and I began shooting arrows and making this supplication: 'Allahumma sahmuka fa-rmi bihi 'aduwwak' (O Allah! This is Your arrow, so destroy Your enemy with it), and the Messenger of Allah (peace and blessings be upon him) was saying: 'Allahumma-stajib li-Sa'd, Allahumma saddid li-Sa'din ramyatahu, iha Sa'd, fidaka abi wa ummi' (O Allah! Answer Sa'd's supplication. O Allah! Make Sa'd's aim true. Shoot on, O Sa'd, may my father and mother be ransomed for you). Whenever I shot an arrow, the Messenger of Allah (peace and blessings be upon him) would say: "O Allah! Make his aim true and answer his supplication. Shoot on, O Sa'd!" until, when I had emptied my quiver, the Messenger of Allah (peace and blessings be upon him) scattered out what was in his own quiver and gave me an excellent, sharp arrow. The narrator says: It was an arrow fitted with feathers, and it was sharper than the other arrows. Imam al-Zuhri (may Allah have mercy on him) says that the arrows Sa'd (may Allah be pleased with him) shot that day numbered one thousand.
This hadith is sahih (authentic) on the condition of Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said: When the people scattered away from the Messenger of Allah (peace and blessings be upon him) on the day of Uhud, I was among the first to return to him. I saw from a distance that a man was coming swiftly behind me like a bird, wanting to reach the Messenger of Allah (peace and blessings be upon him); it was Sayyiduna Abu Ubaydah bin al-Jarrah (may Allah be pleased with him). And I saw another man who was sometimes lifting him (peace and blessings be upon him) up and sometimes setting him down. I said (to myself): If I could not be that man, then I wish it were Talhah, may my father and mother be ransomed for him. When we reached him (peace and blessings be upon him), it was indeed Sayyiduna Talhah who was supporting him (peace and blessings be upon him). Talhah had sustained sixty-six wounds, and one wound had severed his akhal vein. The Messenger of Allah (peace and blessings be upon him) had been struck on his blessed cheek, and two rings of the helmet had sunk into his cheek. When Sayyiduna Abu Ubaydah saw this state of the Messenger of Allah (peace and blessings be upon him), he adjured me by Allah to move away from between him and the Messenger of Allah (peace and blessings be upon him). Then he gripped one ring with his front tooth and pulled it, and it came out, but his own tooth also broke and fell. Then he looked at the other ring and again adjured me by Allah to move away. He pulled that one out too with another tooth, but that tooth of his fell as well. Thus Sayyiduna Abu Ubaydah's front teeth were broken.
This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna al-Zubayr bin al-Awwam (may Allah be pleased with him) that he said: By Allah! I was watching Hind bint Utbah and her female companions running away with their garments lifted (above their shins), and there was not the slightest delay in capturing them. Meanwhile, when we had pushed the enemy back, the archers turned towards the camp, wanting to gather the spoils, and they left our rear exposed to the (enemy) cavalry. So we were attacked from behind, and a caller cried out loudly: Beware! Muhammad (peace and blessings be upon him) has been killed. At this we turned back and the enemy also turned, although before that we had overpowered their standard-bearers, so much so that none of the enemy would come near the standard.
