Frightening the Idolators of Quraysh

Allah threatens the idolators who denied and opposed His Messenger Muhammad ﷺ and He warns them of the punishment and painful torment He sent upon the previous nations who rejected their Messengers. Allah begins by mentioning Musa, upon him be peace, whom He sent along with his brother Harun as a helper -- i.e., as another Prophet who helped and supported him -- but Fir`awn and his chiefs denied them both:

دَمَّرَ اللَّهُ عَلَيْهِمْ وَلِلْكَـفِرِينَ أَمْثَـلُهَا

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.
