Question: Is the fast of the cupper and the cupped broken during the day in Ramadhaan?
What is the ruling, do they continue with their fast broken or make up for that which has passed or what?
Response: The fast of the cupper and the cupped is broken and they must refrain from all that which breaks the fast, and they must make up this day. That which the Prophet said is:
«The cupper and the cupped have broken their fast».
And with Allaah lies all the success, and may Allaah send prayers and salutations upon our Prophet Muhammad (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
