Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said (the narrator is in doubt, perhaps these are the words): Sayyiduna Abu al-Qasim (peace and blessings be upon him) said: "Begin fasting upon sighting it (the new moon of the first) and end fasting upon sighting it, and if it is cloudy, then complete the count to thirty." Imam Daraqutni states: That is, complete the count of thirty days of Sha'ban. This narration, as transmitted from Shu'bah, is authentic; Imam Bukhari (may Allah have mercy on him) has transmitted this narration from Shu'bah through Adam, and in it are these words: "You should complete the count of thirty days of the month of Sha'ban." In this narration, the word "that is" has not been transmitted.
