It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Begin fasting by sighting the moon and stop fasting by sighting the moon. If clouds come between you and the moon, then complete the count (thirty) of the previous month, and do not fast just before (the arrival of) the month of Ramadan. Hatim, the narrator, says: The Prophet (peace and blessings be upon him) meant that the count of Sha'ban should be completed.
