Sahih Muslim Book 7, Hadith Number 3039.

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 recall how I wove garlands for the sacrificial animals (the goats) of Allah’s Messenger (may peace be upon him). He sent them and then stayed with us as a non-Muhrim.
