Surely We have created man from a mingled drop of semen (4) so that We might try him so We made him hearing, seeing (5).
4. Through the sperm of the parents. Through the sperm of the father bony structure is formed, while flesh, blood and hair are formed from the egg of the mother. Therefore, genealogy is perpetuated through the father and not through the mother.
It should be remembered that Hazrat Isa and Sayyeda Hawa are excluded from this natural phenomenon because neither is born from the sperm of a father nor that of the mother. Law is one thing, but power is something else.
5. Almost all human beings can see and hear. The difference is that some listen to the devil and see him, while others listen to the Most Compassionate and behold His Beauty.
Thus, the visual and auditory capacities of human beings differ from one to another. The auditory and visual powers of the Prophets are so strong that they hear and see things from a long distance. Hazrat Sulaiman (On whom be peace) had heard the sound of ants from a distance of five miles. The Holy Prophet صلى الله عليه وآله وسلم saw Allah almighty with his naked eye, but not an eyelash moved.
Says Allah Almighty: "The eye deviated not, nor crossed the limit" (S53:V17). In short, hearing and seeing are different. Observe, the outer vision of some is strong, but others are weak. Then also, the collyrium (surma) to strengthen the outer vision is different to the medicinal root used for strengthening the inner sight.
