Where is the Heart Located?

In this short post we shall be looking at S 33:4. Allah has not made for a man two hearts in his abdomen nor has he made your husbands whom you pronounce zihar upon your mothers. Nor has he made your adopted sons your sons. That is your speech with your mouths but Allah tells the truth. And he guides to the way.

The word translated 'abdomen' is jawf. A dictionary defines it thus:

Translation and Meaning of جوف

In the Arabic Bible the word is used of the belly of the marine creature that swallowed Jonah.

Jonah 1:17 وَأَمَّا الرَّبُّ فَأَعَدَّ حُوتاً عَظِيماً لِيَبْتَلِعَ يُونَانَ. فَكَانَ يُونَانُ فِي جَوْفِ الْحُوتِ ثَلاَثَةَ أَيَّامٍ وَثَلاَثَ لَيَالٍ.

Was the author actually picturing the heart in a man's belly?
