What the passage says
Three verses describing a sequence, each stage named in Arabic.
وَلَقَدْ خَلَقْنَا ٱلْإِنسَـٰنَ مِن سُلَـٰلَةٍ مِّن طِينٍ ثُمَّ جَعَلْنَـٰهُ نُطْفَةً فِى قَرَارٍ مَّكِينٍ ثُمَّ خَلَقْنَا ٱلنُّطْفَةَ عَلَقَةً فَخَلَقْنَا ٱلْعَلَقَةَ مُضْغَةً فَخَلَقْنَا ٱلْمُضْغَةَ عِظَـٰمًا فَكَسَوْنَا ٱلْعِظَـٰمَ لَحْمًا ثُمَّ أَنشَأْنَـٰهُ خَلْقًا ءَاخَرَ ۚ فَتَبَارَكَ ٱللَّهُ أَحْسَنُ ٱلْخَـٰلِقِينَ
And certainly did We create man from an extract of clay. Then We placed him as a sperm-drop in a firm lodging. Then We made the sperm-drop into a clinging clot, and We made the clot into a lump [of flesh], and We made [from] the lump, bones, and We covered the bones with flesh; then We developed him into another creation. So blessed is Allah, the best of creators.
The Arabic terms, on their own terms
نطفة (nuṭfah): in classical Arabic, a small quantity of fluid — a drop remaining in a vessel or waterskin. In this context the reproductive fluid or a drop of it.
علقة ('alaqah): from the root ع-ل-ق, to cling or hang. The lexicons give the sense of something clinging, and also congealed blood; the same root gives 'alaq (a leech) and ta'alluq (attachment).
مضغة (mudghah): from م-ض-غ, to chew — a small morsel, the size of something chewed.
Classical commentators read these as successive stages of formation, described in the vocabulary of ordinary observable things. That is the register of the passage: it is making an argument about the Creator and about resurrection, addressed to people without microscopes.
Ibn Manẓūr, Lisān al-'Arab — entries for نطفة, علق, مضغة · al-Ṭabarī, Jāmi' al-bayān, commentary on Q 23:12–14
What modern embryology observes
After fertilisation, the zygote divides as it travels to the uterus and implants in the uterine wall during the second week — the embryo is genuinely attached to and embedded in maternal tissue at this stage.
Through weeks three and four the embryo folds and forms somites, giving the trunk a visibly segmented external appearance. Cartilage models of the skeleton form from around week six, ossify progressively, and are surrounded by developing skeletal muscle.
These stages are catalogued in the Carnegie staging system and in standard embryology textbooks.

Comparing carefully
There is a real and interesting correspondence in broad shape: a fluid beginning, a clinging stage, a small lump, then skeletal and muscular form. Reading the Arabic and the embryology side by side is a legitimate occasion for reflection.
What we will not do is claim that the passage describes implantation, somite formation or ossification as microscopic processes. The Arabic does not carry that specificity, and classical Tafsir did not read it that way.
We also do not repeat popular claims — a leech-shaped embryo, chew-marks matching somites, bones forming before muscle as a discovery of modern science — as though they were established. Some are contested by embryologists, some by Arabists, and none are needed. Truth does not need exaggeration.

Reflect on the sign
Every person you have ever met passed through stages none of them chose. Who ordered them?

Scientific sources establish empirical claims only. They are never used as evidence for theology, and no verse is re-read to fit a theory.
