Professor and coordinator of Medical Embryology in the Department of Cell Biology, School of Medicine, Georgetown University, Washington DC, USA.
Sheikh Abdul-Majeed A.Zindani met with Professor Goeringer and asked him whether in the history of embryology was there any mention of the different stages of embryonic development, or whether there existed any embryological texts at the time of the Prophet. Sheikh Zindani also asked his opinion regarding the terms the Qur'an uses to describe the different phases of fetal development. After several long discussions, he presented a study at the 8th Saudi Medical Conference:
"...In a relatively few ayahs (Qur'anic verses) is contained a rather comprehensive description of human development from the time of commingling of the gametes through organogenesis. No such distinct and complete record of human development such as classification, terminology, and description existed previously. In most, if not all instances, this description antedates by many centuries the recording of the various stages of human embryonic and fetal development recorded in the traditional scientific literature."
