The alaqah stage mentioned in Qura’n and its interpretations , is considered the most controversial stage of the developing embryo that provoke objections among deniers of the scientific miracles of Qura’n and Sunnah in describing the stages of embryonic development. Some of these objectors , depending upon dictionaries of Arabic language , old commentators and ancient Arab poets , that alaqah means the clotted blood and according to this view , the embryo during alaqah stage is in the form of a clotted blood and this is a scientific error because there is no developmental stage of the embryo in which it is an clotted blood. Another group of objectors , depending upon the explanation given by professor Keith Moore that the embryo at 24 days is like a leech of water pools , although in the lateral view of the developing umbilicus (which is a part of the embryo) it is as large as the part similar to the leech . A third group of objectors describe that the explanation of alaqah to indicate that the embryo is suspended to the uterus was accurately described by Aristotle on the 4th century B.C. and he mentioned the suspension of the embryo in the uterus !!
