﴿ وَلَا يَأْتُونَكَ بِمَثَلٍ إِلَّا جِئْنَٰكَ بِٱلْحَقِّ وَأَحْسَنَ تَفْسِيرًا ﴾

“and [that] they [who deny the truth] might never taunt thee with any deceptive half-truth without Our conveying to thee the [full] truth and [providing thee] with the best explanation.”

Commentary Verse no. 33 supports and accentuates the explanation given above for the wisdom in the gradual revelation of Qur'an in as much as it promises Allah's support in any situation of awkward questions asked by the infidel.
