The above verses refer to a number of senses given to human beings by Allah. These are always referred in a specific order in the Qur'an: hearing, sight, feeling and understanding.
In a paper published in the Journal of the Islamic Medical Association, Dr. Keith Moore states that during the development of the foetus, the eye begins to form after the inner ear has assumed its first form. He says the brain, the centre of feeling and understanding, begins its development after the ear and the eye.94
The foetus' ears begin to develop as early as the twenty-second day of pregnancy and become fully functional in the fourth month. After that, the foetus can hear sounds in its mother's womb. For that reason, the sense of hearing forms before the other vital functions for a new-born baby. The order set out in the Qur'an is striking from that point of view.
