Sahih Muslim 2931

A'isha (Allah be pleased with her) reported that the Messenger of Allah (ﷺ) came out on the 4th or 5th of Dhul'I-Hijja (for Pilgrimage to Mecca) and came to me, and he was very angry. I said:Messenger of Allah, who has annoyed you? May Allah cast him in fire I He said: Don't you know that I commanded the people to do an act, but they are hesitant. (Hakam said: I think that he said: They seem to be hesitant.) And if I were to know my affair before what I had to do subsequently, I would not have brought with me the sacrificial animals, and would have bought them (at Mecca) and would have put off lhram as others have done
