Narrated Aishah, Ummul Muminin: The Messenger of Allah صلی اللہ علیہ وسلم used to count the days in Sha'ban in a manner he did not count any other month; then he fasted when he sighted the new moon of Ramadan; but if the weather was cloudy he counted thirty days and then fasted.

Narrated Imran bin Husain: The Messenger of Allah صلی اللہ علیہ وسلم asked a man: Did you fast the last day of Sha'ban ? He replied: No. He said: If you did not observe a fast, you must fast for a day. One of the two narrators said: For two days.

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 صلی اللہ علیہ وسلم say something (about this matter), or is this something on the basis of your opinion? He replied: I heard the Messenger of Allah صلی اللہ علیہ وسلم as saying: Fast the month (in the beginning) and in the last.

Sulaiman bin Abdur-Rahman al-Dimashqi said about this tradition that al-Walid said: I heard Abu Amr al-Auzai say: The word sirrahu means beginning of the month.

Narrated Kuraib: That Umm al-Fadl, daughter of al-Harith, sent him to Mu'aqiyah in Syria. He said: I came to syria and performed her work. The moon of Ramadan appeared while I was in Syria. We sighted the moon on the night of Friday. When I came to Median towards the end of the month (of Ramadan), Ibn Abbas asked me about the moon. He said: When did you sight the moon ? I said: I sighted it on the night of Friday. He asked: Did you sight it yourself ? I said: Yes, and the people sighted it. They fasted and Muawiyah also fasted. He said: But we sighted it on the night of saturday. Since then we have been fasting until we complete thirty days or we sight it. Then I said: Are the sighting of the moon by Muawiyah and his fasts not sufficient for us? He replied: No. The Messenger of Allah صلی اللہ علیہ وسلم commanded us to do so.
