Musannaf Ibn Abi Shaybah 15044 — A man who buys a sacrificial camel

It is narrated from Ma'iz bin Malik, or Malik bin Ma'iz, al-Thaqafi: My father sent two sacrificial animals (hady) on behalf of himself, his wife and his daughter, and they got lost at Dhu al-Majaz. When the Day of Sacrifice came, he mentioned this to Sayyiduna Umar (may Allah be pleased with him). He said: "Wait today, tomorrow and the day after, for these are the three days of sacrifice. If you find your animals, slaughter both of them; and if you do not find them, then on the third day buy two other animals in their place and slaughter them, and do not come out of ihram until you have slaughtered them. Then, if after slaughtering the purchased sacrifice you find the first animals again, slaughter them too."
