He will Climb the Summit on the Fire and then Fall

 He will be encumbered with climbing the zenith of a mountain in the Fire and then he will fall from the top to the crust of the fire. This is also one of the varieties of punishment in the Hellfire.

I Shall oblige him to (climb a slippery mountain in the Hellfire-called As-Sa´ud, or to) face a severe torment!´´ (Al-Mudahtir: 17)
