[at-Tariq 86:5] So let man consider from what he is created.
[at-Tariq 86:6] He is created from a gushing fluid
[at-Tariq 86:7] That issued from between the loins and ribs.
[at-Tariq 86:8] Lo! He verily is Able to return him (unto life)
[at-Tariq 86:9] On the day when hidden thoughts shall be searched out.
One of the Christian sites spreading false Islamic propaganda had this to say:
“Clearly this verse is incorrect, and clearly it has origins in earlier theories. First of all, for sperm to originate between the back and the ribs would mean that it comes from the kidneys! We now know that semen is produced in the testicles, but people in Muhammad’s time did not know this. Eleven centuries before Muhammad, the Greek physician Hippocrates theorized that sperm passed through the kidneys into the penis. For centuries this was an accepted (and incorrect) belief of the origins of sperm.
There are those who claim Muhammad had no contact with Greeks or Romans. Pre-Islamic Arabia definitely had contact with Byzantium, Syria, Egypt, Persia, and Babylon. There were many Jews and Christians living in the area, and they were familiar with Greek or Roman philosophy. The Christians were connected to Rome. The Jews were connected to Babylon and Persia. It is easy to see how such theories regarding embryonic development may have reached Muhammad.”
This verse is accurate. Semen (the fluid part) is produced in the prostrate gland and seminal vesicals which are located in the abdomen and what’s between the ribs and the backbone? The abdomen and thorax. Now Quran is not trying to be Gray’s Anatomy but the description is correct.
