in the 1940s professor Streeter of the Carnegie Institute of embryology in Washington DC proposed a system for classifying the stages of human development his system arranged human embryos in 23 numbered state stages based on their difference differences in appearance the Carnegie system of classification was used around the world until the 1970s when a more refined system was proposed by dr. Ronan O'Reilly of the Carnegie Institute of embryology now in San Diego California intensive studies of the Quran and hadith in the last four years have revealed a system for classifying human embryos that is amazing since
it was recorded in the seventh century AD although Aristotle the founder of the science of embryology realized that chick embryo was developed in stages from his studies of hens eggs in the fourth century BC he did not give any details about these stages as far as it is known from the history of embryology little was known about the staging and classification of human embryos until the 20th century for this reason the descriptions of the human embryo in the Quran cannot be based on scientific knowledge in the 7th 7th century the only reasonable conclusion is that
these descriptions were revealed to Muhammad from God he could not have known such details because he was an illiterate man with absolutely absolutely no scientific training the first stage is adapt and you'll have to apologize by to my pronunciation this is from sura tarik 6 he is created from a drop emitted this Arabic term refers to the forceful emission of which occurs during ejaculation in the mail and ovulation in the female the male secretions called semen contain the spermatozoa and the female secretions called follicular fluid contained the ovum this is the stage of fertilization and
the nut foot and after they this is what we call the zygote referred to in the quran as the nut and the nut undergoes division which we call cleavage as it passes down the uterine - so these are the stages of the nut but here as it undergoes cell division it is this term is used several times in the quran when referring to the beginning of development after examining all these references it is concluded that nut feh which refers to the small drop of fluid containing the sperm and the ovum the term nut feh is
also used to refer to the dividing zygote as it undergoes cleavage cell division and passes along the uterine tube to enter the uterus this Sarah says then he made his progeny from a quintessence of the nature of fluid despised saliva is an Arabic term refers to the gentle extraction of the germ or sex cells from the millions that are produced there are 300 to 500 million sperms in the ejaculate of a healthy young male only one of these is extracted from the semen to fertilize the old this shows a photograph of the millions of sperm
when they are ejaculated and only one of these several million sperms are is drawn out which is what is suggested by the word saliva the same in the case of the ovary only one of them reaches mature and is expelled from the ovary and it is extracted from the many thousands that are available in the ovary again the idea of extraction or Salalah the next stage is homage I'm judge Sura dare to verily we recreated man of a mixture of a germinal drop I'm Josh and as an Arabic term is used in the Quran that
described the mixing of the sperms and the ovum during fertilization the oval rotates rotates within the fluid containing the sperms until one of them is successful in penetrating it's covering layers which we call the corona radiata and the zona pellucida which is this layer here I'll read it again in English it's surah abasa 19 he created a new individual from nutzy and immediately planned and programmed him that was the first one we had there so elk elk then is an Arabic term which means coming into being and it's used when referring to the fertilized ovum
or zygote here you can see the nuclei from the sperm in the ovum uniting to form a new cell which is the zygote or nut foot and here's the zygote or not again it's just getting ready to divide in the two cells which we call the dividing zygote or the dividing Knutsford the next stage l Tech dear which is in the same verse that it was just repeated this Arabic term means the determination of characters and appears to refer to the fact that from the beginning the zygote or nutfah contains genetic factors in the chromosome
contain the genes which determine the color of the future persons had eyes hair and skin and all its other characteristics such as the appearance of the face and the body now Harth sura how the gareth i 2:23 your wives are as a tilt on to you this Arabic term refers to the plowing of the earth and the sowing of the seed in it this term is used in reference to sexual intercourse following an implantation of the blastocyst sowing of the seed this analogy is a very good one since the blastocyst develops root-like structures called chorionic
villi which derive oxygen and nutrients from the mother's blood just as the roots of the plant shown here drive their nutrients from the soil next is aleca the next slide Alec is sura now who minam aya 14 then we created the drop into a leech like structure then of that leech like structure we made a chewed like substance aleca refers to a leech like appearance especially at about 22 days as shown in this slide this is a leech and this is the human embryo but 23 days they could have to agree that the similarity between
these structures is amazing and that it is truly the human embryo is truly Leeds like the lead spike embryo is attached to the chorionic sack which is embedded in the maternal blood and attached to the maternal endometrium or the lining of the uterus this is vodka stage sir Oh momentum I won the 14 and I repeated that before then we created the drop into a leech like structure then of that leech lake structure we made a tude like substance which you can see here and begins during the six-week next stage is al kissa bill lon
sura al-mu'minun ayah 14 then we close the bones with flesh so in the previous stage then we had the bones and then we covered the bones with flesh so this Arabic term means a clothing with flesh and after the bones form they become surrounded or closed by flesh or muscles which acquire attachments to them these muscle attachment permit movements of the skeleton to occur this is the final stage of development called al nasha then we developed of him another creation a matcha means growth are coming into being this undoubtedly refers to the fetal period when
there is growth and differentiation of the embryo that developed in the embryonic period the rate of body growth during the fetal period is remarkable especially between the ninth and 16 weeks notice how quickly it's growing in this massive stage or fetal period as we call it the next stage is al-kibriya miss sarah says that the duration of pregnancy and separation is 30 months this Arabic term refers to the viability or ability of the human fetus to survive outside the uterus there is no definite time when survival of the fetus is assured but it is generally
accepted now that a fetus that has 24 weeks or older has a reasonable chance of survival survival of fetuses 22 to 24 weeks old has only been become possible in the last few years when better methods of providing care for premature infants we're developed so the period viable embryo or fetus would be here at 24 weeks we used to say 26 28 but now with better incubation some babies at 24 weeks and survive we've even had some at 22 weeks but this takes highly sophisticated incubation to do that so this period then is the period
of viability or the ability of the human fetus to survive the next stage is the Madonna kemiya this stage refers to the final stages of fetal development in the uterus when the fetus could survive if born prematurely but it remains in the uterus where it is supported or nourished by the mother in most cases therefore the uterus acts as an incubator for the premature infant weight gain during these final weeks is phenomenal as the fetus accumulates fat and is gradually prepared for birth this last is surah abasa ayat 19 and 20 from a drop he
created him and immediately planned and programmed him then he makes his passage easy this Arabic term means to make the passage easy it is well known that as the time of birth approaches the maternal tissues of the cervix and the joints of the pelvis become looser so that the passage of the fetus through the fetal canal will be facilitated this process initiated by hormones in the mother's blood accelerates during the early stages of labor or delivery of the baby as the amnio chorionic sack that is the bag of waters surrounding the baby expands near the
time of birth it protrudes into the cervix that is the neck of the uterus and causes it to dilate when the amnio chorionic sack ruptures the amniotic fluid provides a slippery pathway for the fetus to pass along the cervix and vagina to the outside of its mother all the above occurrences facilitate the birth of the baby that is they make the passage easy the stages of embryonic and fetal development mentioned in the quran should be used when teaching muslim students because they are in accordance with our modern understanding of the development before birth it will
also enable muslim doctors and nurses to explain human development to their patients using qur'anic references Muhammad could not have known these facts about human development in the seventh century because most of them were not discovered until the 20th century Muslims and others are justified in concluding that these facts could only have been revealed to Muhammad by the one no one who knows all about us not only about how we developed but how we live in function
