Salaam all,
SPERM or HUMAN?
86:5 So let man observe from what he was created.
86:6 He was created from a fluid, ejected,
86:7 Emerging from between the backbone and the ribs.
86:8 Indeed, Allah, to return him [to life], is Able.
What is emerging between the backbone and the ribs? Some claim it is the baby, others claim it is the sperm. I think both positions are correct. Baby develops down in the uterus located between the backbone and ribs and the following verse supports the human being. Yet the 6th and 7th verses are also connected because the sperm producing testicles are developed from the Mesonephroses. They are at the left and right sides of the baby in the uterus. The mesonephroses are turned into testicles before the baby is born and they get down to the scrotum through the channel called inguinal channel.
