It is narrated from Sayyiduna Zaid bin Arqam (may Allah be pleased with him) that the people said: O Messenger of Allah! What is the reality of these sacrifices? He (peace and blessings be upon him) said: It is the tradition of your father Ibrahim (peace be upon him). They said: What will we get from them? He (peace and blessings be upon him) said: For every hair, a good deed. They said: O Messenger of Allah! What about wool? He (peace and blessings be upon him) said: For every hair of it as well, a good deed will be given.
