It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) was fasting on the occasion of the conquest of Makkah. When he reached a place called Qudayd, a glass of milk was presented to him. The Prophet (peace and blessings be upon him) broke his fast and ordered the people to break their fast as well (and later made up for it).
