The Prophet (saws) said: Do not fast one day or two days just before Ramadan except in the case of a man who has been in the habit or observing a fast (on that day); and do not fast until you sight it (the moon). Then fast until you sight it. If a cloud appears on that day (i.e. 29th of Ramadan) then complete the number thirty (days) and then end the fasting: a month consists of twenty-nine days.

Narrated Anas:
We were with the Prophet (on a journey) and the only shade one could have was the shade made by one's own garment. Those who fasted did not do any work and those who did not fast served the camels and brought the water on them and treated the sick and (wounded). So, the Prophet said, "Today, those who were not fasting took (all) the reward."

Narrated Mu'awiyah:
AbulAzhar al-Mughirah ibn Farwah said: Mu'awiyah 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: Mu'awiyah, did you hear the Messenger of Allah (saws) say something (about this matter), or is this something on the basis of your opinion? He replied: I heard the Messenger of Allah (saws) as saying: Fast the month (in the beginning) and in the last.
