36:65
ٱلْيَوْمَ نَخْتِمُ عَلَىٰٓ أَفْوَٰهِهِمْ وَتُكَلِّمُنَآ أَيْدِيهِمْ وَتَشْهَدُ أَرْجُلُهُم بِمَا كَانُوا۟ يَكْسِبُونَ
al-yawma nakhtimu ʿalā afwāhihim watukallimunā aydīhim watashhadu arjuluhum bimā kānū yaksibūna
On that Day We shall seal up their mouths, but their hands will speak to Us, and their feet bear witness to everything they have done.
This Day, We shall seal up their mouths, and their hands will speak to Us, and their legs will bear witness to what they used to earn. (It is said that one’s left thigh will be the first to bear the witness). [Tafsir At-Tabarî,]
