‘Abdallah b. ‘Amr reported God’s Messenger as saying, “I have been commanded to observe the day of sacrifice as a festival which God has appointed for this people.” A man asked, “Tell me, Messenger of God, if I can get only a female camel lent for milking, am I to sacrifice it?” He replied, “No, but take some of your hair and nails, clip your moustache and shave the hair over your pubes, and that will be a complete sacrifice for you in God’s sight.” Abu Dawud and Nasa’i transmitted it.
