﴿ وَلَقَدْ خَلَقْنَا ٱلْإِنسَٰنَ وَنَعْلَمُ مَا تُوَسْوِسُ بِهِۦ نَفْسُهُۥ ۖ وَنَحْنُ أَقْرَبُ إِلَيْهِ مِنْ حَبْلِ ٱلْوَرِيدِ ﴾

“NOW, VERILY, it is We who have created man, and We know what his innermost self whispers within him: for We are closer to him than his neck-vein.”

(We verily created a man) the child of Adam; and it is said this means: Abu Jahl (and We know what his soul whispereth to him, and We are nearer to him) We are more aware of him and have more power over him (than his jugular vein) and there is nothing closer to man than this jugular vein.
