Study: Threefolds of Darkness

 ... He creates you stage by stage in your mothers' wombs in threefold darkness. That is Allah, your Lord. Sovereignty is His. There is no god but Him. So what has made you deviate? (Qur'an, Az-zumar chapter 39: verse 6)


Fold Number One: Lateral abdominal wall:

In itself three layers of muscles as mentioned in this link (excerpt below) http://www.miraclesofthequran.com/scientific_57.html

The lateral abdominal wall comprises three layers: the external oblique, the internal oblique, and transverses abdominis muscles.

Fold Number Two: Womb

In itself is composed of three special, amazing parts (refer to link above);
 the perimetrium (outer layer of the other two)
the myometrium, (the layer which contracts during birth and menstruation)
the endometrium. (where the fertilized ovum implants itself, see note for amniochorionic membrane)

To my amazement, the Myometrium ALSO consists of three layers! And these three layers are intertwined between circular, longitudinal, oblique (slanting/sloping) and transverse. Longitudinal and Oblique being the most abundant muscle fibers.


Fold Number Three: The amnio-chorionic membrane*
*otherwise known as the waterbag
link: http://en.wikipedia.org/wiki/Decidua

Its three layers:
the amnion (the internal membrane around the fetus),
the chorion (the middle amnion layer)
the decidua (outer amnion layer) (Which has in itself another three layers!) link: http://prosono.ieasysite.com/obg-notes_placenta_membranes.pdf

Note: Placenta contains a layer of the decidua. The placenta has two sides  - the maternal surface and the (smooth) fetal surface. About the placenta: http://php.med.unsw.edu.au/embryology/index.php?title=Placenta_-_Maternal_Decidua

In simple terms, the placenta is like a phone line for communication between mother and child. What comes from the mother is processed and sent to the child through the placenta.

SUBHANALLAH!
