Allah says in the Qur’an, in Surah Al-Ahzab:

“Allah does not place two hearts inside of any man…”

[Qur’an 33:4]

This is an Ayah whose language is easy to understand and appreciate. As you can see, God excludes women from this Ayah. Allah used the word “rajul” to specify men, even though the rest of the passage does mention women. Also, the Qur’an often uses the word “insan” to mention humans in general, but in this passage, He did not.

Lastly, here the word “jawf” is used to speak about the entire body rather than just the chest, even though Allah commonly uses phrases like with the word “chest” in the Qur’an.

So what’s going on? We know that all human beings, regardless of their stages, will have one heart in their chests. However, when talking about the body as a whole, is there a situation where a person has more than one heart in his or her body? Of course! When women get pregnant! Thus, this Ayah is using subtlety in language and the right words for both “man” and “body” to explain that even though this Ayah has a metaphorical meaning, even scientifically, there are never two hearts anywhere inside of a man. The change of either word would be minimal and not truly change the overall metaphorical meaning. However, Allah uses the right combination of words so perhaps even those picky and super technical can’t make an argument against it.
