Sahih Muslim Book 7, Hadith Number 3040.

Chapter : It is meritorious for one who does intend to go himself to send the sacrificial animal to al-Haram.

‘Aisha (Allah be pleased with her) reported: I often wove garlands for the sacrificial animals of Allah’s Messenger (may peace be upon him), and he garlanded his sacrificial animals, and then he sent them and stayed in the house) avoiding nothing which a Muhrim avoids.
