Hadith 948
قالوا يا رسول الله ما هذه الأضاحى ؟ قال : سنة أبيكم ابراهيم ، قالوا ما لنا منها قال بكل شعرة حسنة
The companions asked, "O Messenger of Allah! What are these sacrifices?" He (peace be upon him) replied, "It is the tradition of your father Ibrahim (peace be upon him)." The companions asked, "What reward is there for us in them?" He (peace be upon him) replied, "For every hair, there is a good deed."
