Abu Umair bin Anas says: My Ansari uncles, who were among the Companions, narrated to me that (on the 29th of Ramadan) they did not see the crescent of Shawwal, so the people fasted in the morning. Then, in the latter part of the day, a caravan arrived and they testified before the Messenger of Allah, peace and blessings be upon him, that they had seen the crescent the previous evening. So the Messenger of Allah, peace and blessings be upon him, ordered the people to break their fast and to go out for Eid the next day.
