On the day of the conquest of Makkah, Fatimah came and sat to the left of the Messenger of Allah ﷺ, and Umm Hani sat to his right. A servant girl came with a vessel containing a drink and handed it to him. He drank from it, then passed it to Umm Hani, who also drank from it.She said, "Messenger of Allah, I have broken my fast, and I was fasting."He asked her, "Were you making up a missed fast?"She replied, "No."He said, "Then it does not harm you, if it was a voluntary fast."
