Your Messenger is like the Messenger to Fir`awn, and You know what happened to Fir`awn

Then addresses the disbelievers of the Quraysh, and along with them the rest of mankind,

إِنَّا أَرْسَلْنَا إِلَيْكُمْ رَسُولًا شَاهِدًا عَلَيْكُمْ ...

Verily, We have sent to you a Messenger to be a witness over you,

meaning, witnessing your deeds.

... كَمَا أَرْسَلْنَا إِلَى فِرْعَوْنَ رَسُولًا ﴿١٥﴾

فَعَصَى فِرْعَوْنُ الرَّسُولَ فَأَخَذْنَاهُ أَخْذًا وَبِيلًا ﴿١٦﴾

as We did send a Messenger to Fir`awn. But Fir`awn disobeyed the Messenger; so We seized him with a severe punishment.

أَخْذًا وَبِيلًا severe punishment,

Ibn Abbas, Mujahid, Qatadah, As-Suddi, and Ath-Thawri said:

this means severe.

This means, `you should beware of denying this Messenger, lest you be afflicted by that which befell Fir`awn. Allah seized him with the seizing of One Mighty and Powerful.'

This is as Allah says,

فَأَخَذَهُ اللَّهُ نَكَالَ الاٌّخِرَةِ وَالاٍّوْلَى

So Allah seized him with punishment for his last and first transgression. (79:25)

`Therefore, you will be even more deserving of destruction and ruin if you deny your Messenger, because your Messenger is more noble and a greater than Prophet Musa, the son of `Imran.'

This has been reported from Ibn `Abbas and Mujahid.
