Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) set out from Madinah Munawwarah with the intention of going to Makkah Mukarramah, and he kept fasting during the journey until he reached the place of Usfan. There, the Prophet (peace and blessings be upon him) asked for a vessel of water and placed it on his blessed hand until the people saw it, then he broke his fast. Sayyiduna Ibn Abbas (may Allah be pleased with them both) used to say that whoever wishes may fast, and whoever wishes may not fast. This is the narration of Hasan bin Muhammad. In the narration of Yusuf, it is stated that "The Messenger of Allah (peace and blessings be upon him) traveled in the month of Ramadan," and he kept fasting until he reached the place of Usfan. Then the Prophet (peace and blessings be upon him) asked for a vessel of water and drank it during the day so that the people could see him. Then he continued to leave fasting until he reached Makkah Mukarramah. Sayyiduna Ibn Abbas (may Allah be pleased with them both) used to narrate that the Messenger of Allah (peace and blessings be upon him) kept fasts during travel and also left fasts. Therefore, whoever wishes may fast, and whoever wishes may not fast. Imam Abu Bakr (may Allah have mercy on him) says that this hadith explicitly shows that, according to Sayyiduna Ibn Abbas (may Allah be pleased with them both), the Prophet’s (peace and blessings be upon him) fasting during travel at first and then not fasting later is of the permissible type, and both actions are correct and allowed. It does not mean that breaking the fast upon reaching Usfan (and not fasting for the rest of the journey) abrogates the initial ruling of fasting.
