وَمَا كُنتُمْ تَسْتَتِرُونَ أَن يَشْهَدَ عَلَيْكُمْ سَمْعُكُمْ وَلَآ أَبْصَٰرُكُمْ وَلَا جُلُودُكُمْ وَلَٰكِن ظَنَنتُمْ أَنَّ ٱللَّهَ لَا يَعْلَمُ كَثِيرًۭا مِّمَّا تَعْمَلُونَ
Ye did not hide yourselves lest your ears and your eyes and your skins should testify against you, but ye deemed that Allah knew not much of what ye did.
Surah Fussilat(41:22)
