How can the two narrations reported by Al-Tirmidhi regarding the revelation of Surat Al-Rum be reconciled, given that one indicates its revelation in Mecca, and the other indicates its revelation after the Battle of Badr?

In summary, the correct view is that Surah Ar-Rum is Meccan and its verses were revealed in Mecca. This is based on the authentic narration from Ibn Abbas that confirms it, and on the consensus of the exegetes regarding its Meccan origin. Furthermore, the other narration suggesting its revelation in Medina after the Battle of Badr is weak. Additionally, the anomalous reading mentioned in the weak narration contradicts the consensus of the Qur'an reciters and distorts the meaning.
