In the Quran, God speaks about the stages of man’s embryonic development:
We created man from an extract of clay. Then We made him as a drop in a place of settlement, firmly fixed. Then We made the drop into an alaqah (leech, suspended thing, and blood clot), then We made the alaqah into a mudghah (chewed substance)... 1 (Quran, 23:12-14)
