One of the more popular aspects of the Iﾒjaaz of the Quraan in these times concerns its comments on aspects of science that the Prophet (salallahu alayhi wa sallam) and his people could not have known about. There are a number of books written about this topic, perhaps the most popular being Maurice Bucailles The Bible, the Quran and Science. It should be remembered, however, that the Quraan is not meant to be a book primarily devoted to a discussion of science, but rather a book that is meant for the guidance of mankind.. As such, any references to subjects of a scientific nature are typically brief and not very descriptive.
The Ijaaz. however, appears in the fact that even in these limited descriptions, the Quraan conforms exactly to modern science, and imparts knowledge that was unknown during the lifetime of theProphet (salallahu alayhi wa sallam). These descriptions are free from retroactive ideas that plagued humanity from the earliest of times, such as the concept that the Earth is stationary, and all the other planets and stars rotate about it. There are numerous examples of such verses, such as the description of the formation of human life.
The sperm of man is referred to as a mixture of liquids (Q76:2), since the sperm is composed of various secretions from the testicles, the seminal vesicles, the prostrate and other glands. From the literally millions of sperms produced and ejaculated, only one sperm is actually used in the fertilization process - a very small quantity. This is referred to in a number of verses by the word nutfah (Q75:37), which signifies a small quantity of mixed fluid.
The sperm then joins the female egg, and forms the zygote. This occurs in the mothers womb, a safelodging (Q23:13). The embryo. during its development, is surrounded by three layers: the abdominal wall, the uterine wall, and the placenta, with its chorionoamniotic membranes. These three layers are referred to in the verse, "He created you in the wombs of your mothers, from one stage to another, and all along three veils of darkness surrounded you ...." (Q39[Zumar]:6)
From this, "We made the mixed liquid (zygote) into something which clings (the embryo clingsto the womb by means of the umbilical cord), then We made the thing which clings into a chewed lump of flesh, then We made out of that flesh, bones, then We clothed the bones with flesh, and then We brought it forth as a new creature. So Blessed be Allaah, the best of creators." (Q23[Muminoon]:14)
