Someone observed Sawm on the Two `Eids

Q 1: What is the ruling on someone who observed Sawm (Fast) on the Two `Eids?

A: It is not permissible to observe Sawm on the Two `Eids; and anyone who does so is blameworthy. It is obligatory on them to make Tawbah (repentance to Allah) for this sin. This is because Allah (Exalted be He) has made these days for eating, drinking, and observing Dhikr (Remembrance of Allah). Therefore, whoever observes Sawm on these days disobeys Allah (Exalted be He) and His Messenger (peace be upon him).
