He witnessed the Prophet ﷺ at the place of sacrifice, being a man from the Ansar. The Messenger of Allah ﷺ distributed the sacrificial animals, but neither he nor his companion received any. The Prophet ﷺ then shaved his head, letting the hair fall into his garment, and gave it to him, who in turn distributed portions of it among Some men. He also clipped his nails and gave them to his companion. His hair remains with us to this day, dyed with henna and katam.
أنه شهد النبي ﷺ عند المنحر-وهو رجل من الأنصار- فقسم رسول الله ﷺ ضحايا، فلم يصبه ولا صاحبه شيء، وحلق رأسه في ثوبه، فأعطاه وقسم منه على رجال، وقلم أظفاره فأعطاه صاحبه، فإن شعره عندنا لمخضوب بالحناء والكتم.
Imam Ahmad (16475) and Bayhaqi (1/25) narrated it through the route of Abu Aban Attar, from Yahya bin Abu Kathir, that Abu Salama told him that Muhammad bin Abdullah bin Zayd informed him, from his father, and he mentioned it. Its chain of transmission is sahih. Abu Salama is Abu Salama bin Abdul-Rahman bin Awf Zuhri. Haythami said in Majma (4/39), "Ahmad narrated it, and its narrators are the narrators of the Sahih."Abdullah bin Umar used to hold the view of dividing the udhiya into thirds, eating one third himself, feeding whomever he wished with a third, and giving a third in charity to the poor. Imam Ahmad held this same view, and it is one of the two opinions of Shafii. The other opinion is that one should divide it into halves, eating one half and giving the other half in charity, based on the words of Allah Almighty, "So eat from them and feed the miserable, the poor" [Hajj 22:28].Abu Hanifa and his companions held that the more one gives in charity, the better it is. Ibn Qudama said, "The matter in this is broad, for if one gave the whole of it in charity, or most of it, that would be permissible, and if one ate all of it except a small portion which he gave in charity, that too would be permissible." Al-Mughni (13/380).I have often been asked about giving the meat of the udhiya as a gift to non-Muslims, and I have said that I found nothing that prevents this. Rather, giving it to them as a gift helps win over their hearts, and that is something sought both by the sharia and by common custom.
