quran:85:7 –

And they, to what they were doing against the believers, were witnesses.  

and they themselves, to what they did to those who believed, in God, in the way of torturing them by hurling ˹them˺ into the fire when they did not recant their faith, were witnesses, ˹they were themselves˺ present ˹thereat˺. It is reported ˹in a hadīth˺ that God saved the believers who had been thrown into the fire by taking their souls before they fell into it, and that the fire then rose up and burnt all those ˹sitting˺ around it.
القرآن:٨٥:٧ –

وَهُمْ عَلَىٰ مَا يَفْعَلُونَ بِالْمُؤْمِنِينَ شُهُودٌ  

{وهم على ما يفعلون بالمؤمنين} بالله من تعذيبهم بالإلقاء في النار إن لم يرجعوا عن إيمانهم {شهود} حضور، رُوي أن الله أَنجى المؤمنين الملقين في النار بقبض أرواحهم قبل وقوعهم فيها وخرجت النار إلى من ثَمَّ فأحرقتهم.
