How do we explain to those who celebrated Eid al-Adha on Wednesday, reasoning that its legislation preceded the Hajj and that it has no connection to the Standing at Arafah, that their action was incorrect?

The people of each country should sight the moon and confirm the beginning of the month by sighting it, and their acts of worship will be based on that. They are not obliged to follow a global Day of Arafah. If the countries are under one rule and the ruler orders fasting or breaking the fast, his command must be obeyed. It is obligatory for a Muslim to follow the Muslim community in his country in confirming the beginning of the month. If there is an Islamic body responsible for determining the beginning and end of the month, then it is obligatory to follow it, and if an unintentional error occurs, it is forgiven, based on the saying of the Prophet, peace and blessings be upon him: "Fasting is the day you fast, and breaking the fast is the day you break your fast, and the sacrifice is the day you sacrifice." This is interpreted to mean that fasting and breaking the fast are with the community and the majority of the people.
