It is narrated from Hazrat Aisha (may Allah be pleased with her) that we set out with the Prophet (peace be upon him), and our intention was only to perform Hajj. The Prophet (peace be upon him) ordered that whoever had a sacrificial animal with him should keep his Ihram, and whoever did not have a sacrificial animal should come out of Ihram. On the tenth of Dhul-Hijjah, beef was brought to me. I asked, "What is this?" People informed me that the Prophet (peace be upon him) had sacrificed a cow on behalf of his wives.
