Narrated Muawiyah: Abul Azhar al-Mughirah ibn Farwah said: Muawiyah stood among the people at Dayr Mustahill lying at the gate of Hims. He said: O people, we sighted the moon on such-and-such day. We shall fast in advance. Anyone who likes to do so may do it. Malik ibn Hubayrah as-Saba'i stood up and asked: Muawiyah, did you hear the Messenger of Allah ﷺ say something (about this matter), or is this something on the basis of your opinion? He replied: I heard the Messenger of Allah ﷺ as saying: Fast the month (in the beginning) and in the last.
