Sayyidah Aishah (may Allah be pleased with her) said: We reached Makkah with the Messenger of Allah (peace and blessings be upon him) on the fourth or fifth of Dhu al-Hijjah. One day the Messenger of Allah (peace and blessings be upon him) came to me in a state of anger. I asked: O Messenger of Allah (peace and blessings be upon him), who has angered you? May Allah send him into Hell. He (peace and blessings be upon him) said: "Do you not know that I gave the people an order and they are hesitating over it?" Al-Hakam said: It is as though they were afraid. I think he (peace and blessings be upon him) said: "Had I known beforehand about this matter what I have come to know afterwards, I would not have brought the sacrificial animal with me, but would have bought it here, and then come out of ihram just as they have come out of ihram."
