﴿ حَتَّىٰٓ إِذَا مَا جَآءُوهَا شَهِدَ عَلَيْهِمْ سَمْعُهُمْ وَأَبْصَٰرُهُمْ وَجُلُودُهُم بِمَا كَانُوا۟ يَعْمَلُونَ ﴾

“till, when they come close to it, their hearing and their sight and their [very] skins will bear witness against them, speaking of what they were doing [on earth].”

Till, when they reach it) i.e. the Fire, (their ears and their eyes and their skins testify against them) their ears will testify about what they heard, and their eyes will testify about what they saw and their skins and limbs will tell about what they did (as to what they used to do) with them in their state of disbelief.
