Four times in the Quran, God informs us that He has provided us the hearing, the eye sight, and the brains.
16:78 GOD brought you out of your mothers’ bellies knowing nothing, and He gave you the hearing, the eyesight, and the brains, that you may be appreciative.
17:36 You shall not accept any information, unless you verify it for yourself. I have given you the hearing, the eyesight, and the brain, and you are responsible for using them.
23:78 He is the One who granted you the hearing, the eyesight, and the brains. Rarely are you appreciative.
32:9 He shaped him and blew into him from His spirit. And He gave you the hearing, the eyesight, and the brains; rarely are you thankful.
These three steps also corresponds with actual human development. By about week 16 of pregnancy a fetus’s inner ear structures form, and by 24 weeks, the cochlea, eardrum, ossicles, and other crucial ear structures are fully formed. Eyesight on the other hand isn’t fully formed until week 26.
By the time a baby is born both their hearing and their eyesight is just about fully developed, but what about the brain?
