Al-Hasan said about a person who was in a certain city. He fasted on Monday, and twp persons bore witness that they had sighted the moon on the night of sunday. He said: That man and the people of his city should not fast as an atonement except that they know (for certain) that the people of a certain city of Muslims had fasted on Sunday. In that case they should keep fast as an atonement.

1؎: This fatwa is contrary to the hadith in which it is stated that: The Messenger of Allah (sallallahu alayhi wa sallam) ordered the observance of a fast based on the testimony of one man, and ordered the celebration of Eid based on the testimony of two men, meaning: the matter depends on truthful testimony, not on the action of a large crowd.
