Qaf - 50:16

وَلَقَدْ خَلَقْنَا الْإِنسَانَ وَنَعْلَمُ مَا تُوَسْوِسُ بِهِ نَفْسُهُ وَنَحْنُ أَقْرَبُ إِلَيْهِ مِنْ حَبْلِ الْوَرِيدِ
[50:16]
And certainly We created man, and We know what his mind suggests to him, and We are nearer to him than his life-vein.
It was We Who created man, and We know what dark suggestions his soul makes to him: for We are nearer to him than (his) jugular vein.
We verily created man and We know what his soul whispereth to him, and We are nearer to him than his jugular vein.
