“It was We Who created man, and We know what dark suggestions his nafs (self) makes to him: for We are nearer to him than (his) jugular vein,” (50:16).
“And why the jugular? Why does Allah (swt) choose to mention this part of us? The jugular vein is the most important vein that brings blood to the heart. If severed, we die almost immediately. It is literally our lifeline. But Allah (swt) is closer. Allah (swt) is closer than our own life, than our own Self, than our own nafs. And He is closer than the most important pathway to our heart.” -Yasmin Mogahed
