My dearest Ustazah,
Assalamualaikum,

Hope you get this e-mail in your best Eman and health. Ameen.
There are verses from sorah السجدة, البقرة ,النحل which made me inquisitive day by day why Allah (S.W.T) has mentioned these 3 organs/powers," hearing, sight and heart" of Human body repeatedly and hearing is always before sight . Verses are:

9 # السجدة Then He fashioned him in due proportion, and breathed into him the soul and He gave you hearing (ears), sight (eyes) and hearts. Little is the thanks you give!
78 # النحل And Allah has brought you out from the wombs of your mothers while you know nothing. And He gave you hearing, sight, and heartsthat you might give thanks (to Allah).

and Allah (S.W.T) wants us to be thank full otherwise He’ll seal them. As in:

7 #البقرة Allah has set a seal on their hearts and on their hearing and on their eyes there is a covering. Theirs will be a great torment.

I was wondering Why didn't Allah (S.W.T) talk about to be thankful or set a seal on the Liver, Lungs or Kidney ect ,these are important organs too.
Alhumdullilah ,He listened Dua.

I got a little sense of their importance and connection with each other.

As we know:
The processes of going to sleep or G. Anesthesia, Ear is the last organ which gets aloof while Eyes close immediately and when we try to wake up Ears are the first to alert while eyes are still closed.Heart stops working only at the time of death otherwise whatever happens, it keeps beating.

Heart is the first functional part in an embryo which can be seen as flickering in the embryonic chest by an ultrasound performed even during the 4th week of pregnancy, means 1st month. After that ,during 10-12 week mean approximately 3rd month ears start functioning and baby can hear. While, approximately during 29th week (The 7th month) eyelids, open and close. Again ears start functioning before eyes.

Ref: Moore, Keith L. The Developing Human: 3rd Edition. Philadelphia PA (He is the Scientist who got help from Quran,during the studies of Embryology.)

Another interesting Medical fact is: the patient who lost hearing due to the damage of hearing nerve (vestibule cochlear) may cause the following symptoms too:
Nystagmus means involuntary eye movements. Their eye movements are not in their control anymore.
Vertigo is a type of dizziness as well as difficulties standing or walking.
Ref: "Core Curriculum: Inner Ear Disease — Vertigo". Baylor College of Medicine. 2006-01-23. http://www.bcm.edu/oto/studs/vertigo.html. Retrieved 2007-09-19.

Allahu Akber, how hearing is controlling the sight and walk of life. Seal of ears can be the cause of improper vision which can easily deviate us from Siratul Mutaqeem.

Whatever,we Listen and See our heart process it. We start saying it and show by our Actions.
Ya Sameeo' Ya Baseero guide us, to use our powers properly so We'll be among Mulihoon.

May Allah bless you and your family with all the Hassanat of Dunya and Akhira as you make us listen and see the"The Elm" which has changed our hearts and help us to be thank full.

Wassalm,
