(34) باب إِذَا صَامَ أَيَّامًا مِنْ رَمَضَانَ ثُمَّ سَافَرَ
Narrated Ibn `Abbas:
Allah's Messenger (ﷺ) set out for Mecca in Ramadan and he fasted, and when he reached Al-Kadid, he broke his fast and the people (with him) broke their fast too. (Abu `Abdullah said, "Al-Kadid is a land covered with water between Usfan and Qudaid.")
