We used to garland the goats and send them (to Mecca), and Allah's Messenger (ﷺ) stayed back in Medina as a non-Muhrim ard nothing was forbidden for him (which is forbidden for a Muhrim).
Sahih Muslim Book 15, Hadith 408
← Previous Hadith Allah's Messenger (may peace be upon, him) sent some goats as sacrificial animals to the House and He garlanded them.

Sahih Muslim Book 15, Hadith 407 Next Hadith → It is not as Ibn 'Abbas (Allah be pleased with them) had asserted, for I wove the garlands for the sacrificial animals of Allah's Messenger (ﷺ) with my own hands. Allah's Messenger (ﷺ) then garlanded them with his own hands, and then sent them with my father, and nothing was forbidden for Allah's Messenger (ﷺ) which had been made lawful for him by Allah until the animals were sacrificed.

Sahih Muslim Book 15, Hadith 409
