And We have already created man and know what his soul whispers to him, and We are closer to him than [his] jugular vein
Imaam al-Tabari says that the scholars of the Arabic language have differed in regards to the meaning of the portion of the Verse which reads:
"and We are closer to him than [his] jugular vein"
وقال آخرون: بل معنى ذلك ( وَنَحْنُ أَقْرَبُ إِلَيْهِ مِنْ حَبْلِ الْوَرِيدِ ) بالعلم بما تُوَسْوس به نفسه
A group has said that the meaning of that ("and We are closer to him than [his] jugular vein") is by means knowledge of that which his soul whispers to him
