Sahih Muslim Book 7, Hadith Number 3044.

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

Masruq reported: I heard ‘Aisha (Allah be pleased with her) clapping her hands behind the curtain and saying: I used to weave garlands for the sacrificial animals of Allah’s Messenger (may peace be upon him) with my own hands, and then he (the Holy Prophet) sent them (to Mecca), and he did not avoid doing anything which a Muhrin avoids until his animal was sacrificed.
