The ruling on slaughtering before the Day of Sacrifice, citing the hadith: (Do it, there is no harm)

Question : Those who say that slaughtering is permissible, for example, before the festival, before the day of the festival after the 'Umrah, or we have found people who said, for the sake of...

Answer : These people, may Allah bless you, say that just as you permitted fasting for the one who did not find the sacrificial animal, which is a substitute, the thing being substituted is all the more so.

But these people are certainly refuted by the fact that the Messenger (peace and blessings be upon him) brought forward [the slaughter] on the fourth of Dhu al-Hijjah and said to his Companions: "If I did not have the sacrificial animals with me, I would have brought them with you, and you would not have slaughtered the sacrificial animals." Yes.
