Mention of the battle of Hunayn and the Ansar gathering around the Prophet (peace and blessings be upon him)

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that he said: On the day of the battle of Hunayn, the Messenger of Allah (peace and blessings be upon him) called the Ansar and said: "O company of the Ansar!" They replied: "Labbayk (here we are at your service), may our fathers and mothers be sacrificed for you, O Messenger of Allah!" He (peace and blessings be upon him) said: "Turn your faces towards Allah and His Messenger, and He will admit you into gardens beneath which rivers flow." So they turned with fervour, until he (peace and blessings be upon him) was surrounded by a throng whose shoulders were rubbing against one another (because of the crowding), and they fought steadfastly until Allah defeated the polytheists.
This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it; and the narration of Mubarak bin Fadalah is a supporting witness (shahid) for it.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that he said: On the day of the battle of Hunayn, the people of Makkah and the people of Madinah met the enemy, and the fighting grew intense, and the Muslims (at first) turned their backs. Then the Messenger of Allah (peace and blessings be upon him) called out to the Ansar and said: "O company of Muslims! I am the Messenger of Allah." They replied: "By Allah! It is to you that we have come." Then, with their heads lowered, they fought until Allah granted them victory.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) had finished with the conquest of Makkah, he (peace and blessings be upon him) headed for Hunayn. Meanwhile Malik bin Awf al-Nasri had gathered Banu Nasr, Jusham, Sa'd bin Bakr, some groups of Banu Hilal and people of Banu Amr bin Asim bin Awf, and the allies of the tribe of Thaqif and Banu Malik had also joined them in full force. Then he set out against the Messenger of Allah (peace and blessings be upon him), taking with him their wealth, women and children. When the Messenger of Allah (peace and blessings be upon him) received news of them, he (peace and blessings be upon him) sent Sayyiduna Abd al-Rahman bin Abi Hadrad al-Aslami (may Allah be pleased with him) and said: "Go and mingle with these people until you bring us certain news of them." He went and stayed there for a day or two, then came back and told him (peace and blessings be upon him) the situation. The Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Umar bin al-Khattab (may Allah be pleased with him): "O Umar! Do you hear what Ibn Abi Hadrad is saying?" Sayyiduna Umar (may Allah be pleased with him) said (in astonishment): "Ibn Abi Hadrad has lied." At this Ibn Abi Hadrad (may Allah be pleased with him) said: "If you are calling me a liar, then you have at times called a liar one (the Prophet (peace and blessings be upon him)) who is better than me." Sayyiduna Umar (may Allah be pleased with him) said: "O Messenger of Allah! Do you hear what Ibn Abi Hadrad is saying?" The Messenger of Allah (peace and blessings be upon him) said: "O Umar! You were once astray, and then Allah, the Mighty and Majestic, guided you." Then the Messenger of Allah (peace and blessings be upon him) sent word to Safwan bin Umayyah and asked him for one hundred coats of armour along with the necessary war equipment that goes with them. He asked: "O Muhammad (peace and blessings be upon him)! Are you taking this by force?" He (peace and blessings be upon him) said: "No, rather it is a loan with a guarantee of return, 'ariyah madmunah (a guaranteed loan), until we return it to you." Then the Messenger of Allah (peace and blessings be upon him) set out (with the army).
