Many diverse subjects are mentioned in the Qur’an while also inviting people to believe. Sometimes the heavens, sometimes animals, and sometimes plants are mentioned as evidence of Allah’s existence. In many of these verses, people are called upon to consider their own creation. They are often reminded how man came into the world, which stages he has passed through, and what his essence is:
It is We Who have created you. Why, then, do you not accept the truth? Have you ever considered that [seed] which you emit? Is it you who create it? Or are We the Creator? (Qur’an, 56:57-59)
The miracle of man’s creation is emphasised in many verses. Some of the information within these verses is so detailed that it was impossible for anyone living in the 7th century to have known it. Examples of these are as follows:
1. Man is not created from the entire semen, but only a very small portion of it (sperm).
2. It is the male that determines the sex of the baby.
3. The human embryo adheres to the mother’s uterus like a leech.
4. The embryo develops in three dark regions in the uterus.
The items of information just quoted were far above the level of learning of the people living at that time. The discovery of these facts could only become possible by the technology attained in the 20th century.
