Zaid b. Arqam said the companions of God’s Messenger asked him the significance of these sacrifices and he replied, “It is a custom which has come down from your father Abraham." They asked what reward they would receive for them and he replied, “For every hair you will receive a blessing." They asked about wool, and he replied, “For every strand of wool you will receive a blessing." Ahmad and Ibn Majah transmitted it.
