Sahih Muslim Book 7, Hadith Number 3035.

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

Abd al-Rahman b. al-Qasim reported on the authority of his father that he heard ‘Aisha (Allah be pleased with her) saying: I used to weave garlands for the sacrificial animals of Allah’s Messenger (may peace be upon him) with these hands of mine, but he (Allah’s Apostle) neither avoided anything nor gave up anything (which a Muhrim should avoid or give up).
