May God bless him and grant him peace, in the position of his call to the monotheists, as he called them to pronounce it as an act of sacrifice, but they had no knowledge of that. So, one time, he gave a sheep to the house, which was a pure animal in whose pens it is permissible for us to pray, so it was like offering sacrifice to the monotheists.

Muslim came out. On the authority of Aisha, she said: The Messenger of God, may God bless him and grant him peace, presented a sheep to the House, so he imitated it

And imitation is for sheep, meaning this is their characteristic that necessitated their proximity to be an offering.
