question #3 Sahih Muslim 1211v, Book 15, Hadith 140 : What considerations did the Prophet Muhammad (ﷺ) have regarding the sacrificial animals during Hajj?

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.
