the month of Dhu al-Hijjah is likewise not established except by two witnesses. Thus, if a person alone sees it, the beginning of the month is not established by his testimony. Accordingly, if a man stands at Arafah on what is, according to him, the ninth day but is, according to the people, the eighth, his standing does not suffice.
If he wishes to fast on what is, according to him, the ninth day but is, according to the people, the eighth, intending it as the Day of Arafah, this does not suffice as fasting the Day of Arafah. But if he fasts on what is, according to the people, the ninth day, though it is according to him the tenth, is it permissible for him to fast it?

His words, “upon every Muslim”: the preposition “upon” is superfluous; that is, it is obligatory for every Muslim.
This is the first condition. The opposite of Islam is disbelief; therefore, fasting is neither obligatory upon the disbeliever nor valid from him.
By our saying that it is not obligatory upon him, we mean that we do not require him to fast while he remains in disbelief, nor do we require him to make it up after accepting Islam. The evidence for this is the saying of Allah, the Exalted: “And what prevented them
