That is because Allah hath revealed the Scripture with the truth. Lo! those who find (a cause of) disagreement in the Scripture are in open schism.

Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
“O you who believe! Observing As-Saum (the fasting) is prescribed for you as it was prescribed for those before you that you, may become Al- Muttaqun (V.2:183).
Narrated Ibn `Umar:
Fasting was observed on the day of 'Ashura' (i.e. 10th of Muharram) by the people of the Pre-lslamic Period. But when (the order of compulsory fasting) in the month of Ramadan was revealed, the Prophet said, "It is up to one to fast on it (i.e. day of 'Ashura') or not."
