Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) asked: How many days are left for the month (to end)? The Prophet Muhammad (peace and blessings be upon him) meant the month of Ramadan. We replied: Twenty-two (22) days have passed and eight days are left. The Prophet Muhammad (peace and blessings be upon him) said: Twenty-two (22) days have passed and seven days are left; seek it in tonight. Then the Prophet Muhammad (peace and blessings be upon him) said: The month is like this and like this. He said this three times, twice indicating ten and once indicating nine.
