Abu ‘Umair b. Anas told on the authority of some of his paternal uncles who were companions of the Prophet that some men came riding to the Prophet and testified that they had seen the new moon the previous day. He therefore commanded the people to break the fast and go out to their place of prayer in the morning. Abu Dawud and Nasa’i transmitted it.
