Lady Umm Hani (may Allah be pleased with her) said: On the day of the conquest of Makkah, Lady Fatimah (may Allah be pleased with her) came and sat on the left side of the Messenger of Allah (peace and blessings be upon him), and Lady Umm Hani (may Allah be pleased with her) was on the right side. She said: A slave girl brought a water vessel and presented it to the Prophet (peace and blessings be upon him). He drank from it, then gave it to Lady Umm Hani (may Allah be pleased with her), and she also drank water from that vessel. Then she said: O Messenger of Allah! I was fasting, and now I have broken my fast? The Prophet (peace and blessings be upon him) said: "Was it a make-up (qada) fast?" She replied: No. He said: "Then there is no harm, as it was a voluntary fast." Imam Darimi (may Allah have mercy on him) said: This is also my opinion (i.e., if a voluntary fast is broken, then there is no harm).
