Al-Hajj: 68

(And if they dispute with you) concerning the matter of religion, now that the truth has become manifest and the proof is established, (then say) to them—by way of a warning—("Allah is most knowing of what you do") of the falsehoods, among which is this disputation; He will recompense you for them. If this is intended as a promise of retribution, as Abu Hayyan has asserted, then it is abrogated by the Verse of Fighting.
