A man reported,

The people disagreed about the last day of Ramadan, then two Arabis came and testified before the Prophet ﷺ, swearing by Allah that they had sighted the crescent moon the previous evening. So the Messenger of Allah ﷺ ordered the people to break their fast.Khalaf added in his version, "and to go out to their prayer ground in the morning."
