﴿ ٱلْيَوْمَ نَخْتِمُ عَلَىٰٓ أَفْوَٰهِهِمْ وَتُكَلِّمُنَآ أَيْدِيهِمْ وَتَشْهَدُ أَرْجُلُهُم بِمَا كَانُوا۟ يَكْسِبُونَ ﴾

“On that Day We shall set a seal on their mouths but their hands will speak unto Us, and their feet will bear witness to whatever they have earned [in life].”

Today We shall seal up their mouths namely the mouths of the disbelievers for their saying By God our Lord we were never idolaters!’ Q. 623; and their hands shall speak to Us and their feet shall bear witness as will other parts of their bodies concerning what they used to earn and so each limb will speak of that sinful action which issued from it.
