Fussilat (Explained in detail)

29. And those who disbelieve will say: “Our Lord! Show us those among jinn and men who led us astray: that we may crush them under our feet so that they become the lowest.”

Disbelievers wish to know those who led them to error so that they may take their vengeance upon them. Those who led people in this world were highly respected to those in error but the latter wish to denigrate the former in the Hereafter.

The blessed Verse in question is saying that when disbelievers find themselves in the shadows of Abyss and the blazing Hellfire lose their hope of deliverance and utter such words out of desperateness wishing to find those who led them to such unfortunate state and take their vengeance upon them for having them misled and crush them and send them to the lowest level of Hell.

They will apparently say that those who were their chiefs and leaders seduced them and they wish that they be crushed by them so that they may be happy to take their vengeance upon them.
