*4952 - Abdullah Yusuf Ali commentry
Allah created man, and gave him his limited free will. Allah knows inmost desires and motives of man even better than man does himself. He is nearer to a man than the man's own jugular vein. the jugular veis is the big trunk vein, one on each side of the neck, which brings the blood back from the head to the heart. the two jugular veins correspond to the two carotid arteries which carry the blood from the heart to the head. as the blood-stream is the vehicle of life and consciousness, the phrase "nearer than the jugular vein" implies that Allah knows more truly the innermost state of our feeling and consciousness than does our own ego.
