Qaf 50:18
مَّا يَلْفِظُ مِن قَوْلٍ إِلَّا لَدَيْهِ رَقِيبٌ عَتِيدٌ
Ma yalfithu min qawlinilla ladayhi raqeebun AAateed
"He [i.e., man] utters no word except that with him is an observer prepared [to record]."
Qaf 50:18, translation by Sahih International
A short reflection
He utters not a word except that with him is an observer prepared. Every word, recorded.
