From the mudghah stage, `idhaam are created. This is the next stage. The word `idhaam in the Arabic language means bone, and is specifically applied to the bones of the hands and feet, or of the arms and legs of an animal, upon which is the flesh.70

The `idhaam stage pertains to the development of the axial and limb skeleton, occuring at around the 5th week. Barry Mitchell and Ram Sharma explain:

The origin of mesenchymal cells forming the skeletal tissues varies in different regions of the body. Mesenchymal cells forming the axial skeleton arise from the mesodermal somites, whereas the bones of the appendicular skeleton are derived from the somatopleuric mesenchyme of the lateral plate mesoderm. After reaching their destination the mesenchymal cells condense and form models of bones. The subsequent differentiation of mesenchymal cells into chondroblasts or osteoblasts is genetically controlled.71.

‘Limb bones’ is the specified meaning of the word `idhaam, and therefore can refer to the development of the limb buds which give rise to the development of the limbs and the appendicular skeleton. Barry Mitchell and Ram Sharma elaborate on the formation of the limb and appendicular skeleton:

The appendicular skeleton consists of limb girdles and the bones of the limbs. The bones of the appendicular skeleton develop from mesenchymal condensations which become cartilaginous models.72 [See Figure 7]

John Allen and Beverley Kramer also comment on limb bone formation.

The limb mesenchyme is at first a homogenous mass but soon condensations occur in it and these chondrify to form cartilaginous models of the various bones. Each cartilage model is surrounded by perichondrium which is a condensation of mesenchyme. An ossific centre (primary ossification centre) is formed upon each cartilage model by the ingrowth of osteobalsts (bone-forming cells) from the surrounding mesenchyme. The surrounding mesenchyme is now termed periosteum (surrounding the bone). Osteoblasts now produce bone which give rise to the skeletal elements of the limbs. 73.

There are clear parallels between the qur'anic `idhaam stage and the view modern embryology takes i.e. the development of the axial, limb and appendicular skeleton.

The `idhaam stage: The formation of the axial, limb and appendicular skeleton.

A common misconception, usually made by non-Arabists, is that this verse can be literally translated as “and We made that lump into bones”. From this, they conclude that this verse is unscientific because a lump of flesh cannot turn into a mass of bones. However, this is based upon a crude understanding of Arabic grammar and the Qur’an's eloquence. This verse, from a grammatical perspective, has the meanings of: “and We made of/from/out of the lump bones”.

This is why Yusuf Ali translates this verse as “then we made out of that lump bones”74; Shakir translates it as “then We made (in) the lump of flesh bones”; and A J Arberry, in his translation of the Qur’an which is still used by academics today, translates this verse as “then We created of the tissue bones”.75

Another proposition from commentators is that at this stage there are no real bones. It is argued that the apparent bones are mere cartilage as ossification is incomplete and, as such, the Qur’an must therefore be inaccurate. Although a valid contention, it is misplaced. `idhaam encompasses the cartilaginous form of the bones as the skeletal framework is put in place. Additionally, the process of ossification begins by the 8th week,76 continuing on after birth, with the eventual completion of the ossification process at around puberty. Barry Mitchell and Ram Sharma explain:

The centres of ossification first appear in the limb bones during the eighth week. By the twelfth week, the shafts of the limb bones are ossified, though the carpal bones of the wrist remain cartilaginous until after birth. The ossification of the three largest tarsal bones of the ankle begins about 16 weeks, but some of the smaller tarsal bones do not ossify until 3 years after birth.77.

From this perspective, it would be a medical absurdity to assume newborns or young teenagers do not have bones simply because they require ossification, especially since ossification completes at the end of the growth-spurt of puberty. Nevertheless if this were the case, and we are to take this stage as being ‘boneless’, as it were, the derisions of the word `idhaam allow for an all encompassing interpretation because the “cartilaginous models of the various bones”78 is included in its meaning.
