Sayyiduna Rafi‘ bin Khadij (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings of Allah be upon him) said:“Count the days of Sha‘ban for Ramadan, do not fast before the month of Ramadan begins. When you see it (the crescent of the first), then start fasting, and when you see it, then stop fasting. If it is cloudy for you, then complete thirty days, and then stop fasting, because sometimes the month is like this, and sometimes like that.”The third time, the Noble Prophet (peace and blessings of Allah be upon him) bent his thumb inward.
