Mu’adh bin Muhammad reports: I asked Zuhri about the sighting of the Shawwal moon, if it is seen in the morning, so he said: I heard Sa’id bin al-Musayyib say: “If the Shawwal moon rises after true dawn until ‘Asr (the narrator is in doubt, perhaps the words are: until Maghrib), then the moon will be counted for the coming night.” Imam Abu ‘Abdullah says: There is consensus on this matter.
