﴾Is he who was dead (without Faith by ignorance and disbelief) and We gave him life (by knowledge and Faith) ﴿

[Al-An'am, 122]

﴾but you cannot make hear those who are in graves.﴿

[Fatir, 22]

 Man without a connection with Allah is just a living-dead or he is like the wrecked house. Allah says:

﴾O you who believe! Answer Allah (by obeying Him) and (His) Messenger when he (peace be upon him) calls you to that which will give you life﴿

[Al-Anfal, 24]

 Pay attention to this Ayah:

﴾But if they answer you not (i.e. do not believe in your doctrine of Islamic Monotheism, nor follow you), then know that they only follow their own lusts.﴿

[Al-Qasas, 50]

 You are before two options: you respond either to Allah or to your desires, you obey either Allah or your lusts, you are submitted either to Allah and longing for the Hereafter, or to your pleasures and yearning for the worldly life and you respond either to the call of the Divine Revelation or to the call of your lusts. Allah says:

﴾O you who believe! Answer Allah (by obeying Him) and (His) Messenger when he (peace be upon him) calls you to that which will give you life, and know that Allah comes in between a person and his heart (i.e. He prevents an evil person to decide anything). ﴿

[Al-Anfal, 24]

The prudent is the one who calls himself to account from time to time:

  Dear brother, I hope that you, me included, make a review of all your deeds from time to time, ponder over the performance of Salah and wonder, "Is our performance of Salah is the one decreed by Allah?" A brother told me once that when he performed Salah in the Sacred Haram, he wept abundantly, and he went on saying, "This is the Salah expected by Allah. It makes you feel as if you own everything." A great God calls you five times daily to perform Salah, so do you think He calls you to perform meaningless moves which starts with Takbeer and ends with Tasleem and during it you are occupied with all sorts of notions and concerns? Absolutely, He does not. 

 A man doubted how many Rak'at he performed in Maghrib Salah, wondering whether he prayed two or three Rak'at, but then he remembered that he prayed three Rak'at saying, "I had three boxes at work and each one of them had a problem, so I solved the first problem in the first Rak'ah, then I solved the second problem in the second Rak'ah, and I solved the third one in third Rak'ah, so I must have prayed three Rak'at."
  He was preoccupied with thoughts which have nothing to do with Salah. Is this performance of Salam meant by Allah, Glorified and Sublime be He? When someone is given the grace of performing Umrah or Hajj,, he will feel how close he is to Allah while performing Salah in Allah's Sacred House, because it is performed with lots of tears, and during it he establishes a connection with Allah. Thus, this is the performance of Salah meant by Allah.
Salah is accepted only when man is humble to Allah and when he avoids Prohibitions:

  When you say "man", this word includes all people on earth, but when you say "a Muslim man", the number comes down to one billion and 500 millions, and when you say "An Arab Muslim man" the number will become only 500 millions, and by adding another characteristic, saying, "An educated Arab Muslim man", the circle becomes smaller, and when you add a doctor or a cardiologist the circle will become very small and it will include few people only. Compare this example to the following Ayah: 

﴾Verily, man (disbeliever) was created very impatient* Irritable (discontented) when evil touches him* And niggardly when good touches him* Except those devoted to Salat (prayers)﴿

[Al-Ma'arij, 19-22]

 Though Muslims are one billion and 500 millions, only 500 millions among them pray properly:

﴾Except those devoted to Salat (prayers)* Those who remain constant in their Salat (prayers)* And those in whose wealth there is a known right* For the beggar who asks, and for the unlucky who has lost his property and wealth, (and his means of living has been straitened)* And those who believe in the Day of Recompense, And those who fear the torment of their Lord* Verily! The torment of their Lord is that before which none can feel secure* And those who guard their chastity (i.e. private parts from illegal sexual acts)* Except with their wives and the (women slaves and captives) whom their right hands possess, for (then) they are not to be blamed* But whosoever seeks beyond that, then it is those who are trespassers* And those who keep their trusts and covenants* And those who stand firm in their testimonies* And those who guard their Salat (prayers) well* Such shall dwell in the Gardens (i.e. Paradise) honoured.﴿

[Al-Ma'arij, 22-35]

  The following Qudsi Hadith describes the one whose Salah is accepted by Allah:

((Not all those who pray are prayers, as I accept Salat from only those whose Salat make them humble to My Greatness, who do not follow their desires, who do not insist on disobeying Me, who feed the hungry, who cloth up the needy, who are merciful to the injured, and who house the stranger. Only if all are done for my Sake, by My Glory and My Loftiness the light of his face will be to Me brighter than the sun. I will turn his recklessness to patience and darkness to light, and if he supplicates Me, I will answer him, if he asks Me, I will give him, if he swears by My Name, I will respond to him. I will keep him close to Me and let My angels protect him. He is to Me like Paradise whose fruits do not lack and whose state never changes.))

[Ad-Dailami by Harithah bin Wahab]

 Dear brother, our blessed meeting today is about the fruits reaped upon establishing a connecting with Allah.

The topic of the scientific inimitability of the Quran:

  Now let us move to the scientific topic. 

Pondering over the creation makes us witness Allah's Greatness:

  Dear brother, when someone seeks the religious knowledge, he will study Fiqh (Jurisprudence), interpretation of the Quran, Hadith, Sirah (Prophetic biography) and other majors like Al-Fiqh Al-Muqaran (Comparative Jurisprudence), the History of Shari'ah or Usul Al-Fiqh (the Principles of Jurisprudence), etc. However, the majority of Muslims forget that the essence of religion is to know Allah and to get acquainted with Him. 

 I repeat frequently that knowing the Commander (Allah), before knowing His Orders, will make you obey Him submissively, but if you know the Orders without knowing the Commander (Allah), you will avoid obeying the orders skillfully. In fact, there are about 1000 Ayat in the Quran which revolve around the Signs of the universe in the heavens and the earth and the Signs of the creation of man, which means that we should ponder over the creation of the heavens and the earth.

 I keep saying to you that reflecting on the creation of the heavens and the earth puts us face to face with the Greatness of Allah; better yet it is considered the shortest path to know Allah and the widest gate through which we can reach Allah. Pay attention to the fact that there is the knowledge of Allah which is the basic ground of religion, the knowledge of Allah's Orders which is the base of Shari'ah and the knowledge of His Creations which is the reason behind mending our worldly life. The Muslim needs desperately to know Allah, so that he can become upright on His Path. As I have just said, when you know the Commander and then you know the Orders, you will obey the Commander (i.e. Allah) submissively.

The nose is one of Signs which indicate Allah's Greatness:

  Let me talk about the nose of man. The nose has a very delicate system. In the nose there are interior nested surfaces, so the air has to pass through a long distance inside the nose, but why is that? Man's average inner temperature is 37 degrees centigrade, and in winter man inhales very cold air whose temperature is close to zero, and by passing through all this distance inside the nose, the air is heated in order to reach the lungs in a suitable temperature.

 These nested surfaces have a privilege, for they are provided with blood vessels which feed the muscles, and when the latter expand, the blood flow increases, making man's nose in winter red, but do you know where does this red color come from? It comes from the widened blood vessels in the nose, and they become wide in order to bring warm blood to these surfaces through which the air is heated. Thus, it is not healthy to inhale air in winter through the mouth, because it causes many diseases, while the right thing to do is to inhale air through the nose due to the many privileges it has. 

 The inner surfaces are covered with sticky mucus which traps the dust and dirt particles found in the inhaled air. Thus, when man is amid dusty weather, the dust particles are stuck on the mucus of the nose, and when he tries to clean his nose, he will see that the discharges are dark because of the stuck dust. There is profound wisdom behind having mucus in the nose, and had some dust particles managed to get through the nose and survived the mucus, what would have stopped them? Here comes the role of the hairs in the nose. Therefore, in the nose there is mucus on the inner surfaces, the hairs, the blood vessels and muscles, so that the air will pass through a long distance in order to be heated before entering the lungs. It is just a nose, yet you can sense the Divine Planning, the Divine Wisdom, the Divine Mercy and the Divine Knowledge upon reflecting on the functions of the nose.

The function of the smelling nerves:

 Man also uses his nose to smell, but how many smell nerves does the nose have? It has 20 million smell nerves, each one of them ends with 7 cilia, and each one of the latter is dipped in a mucus substance which interacts with the smell and produces a geometric compound which is the code of this smell. Then, this compound is transferred to the brain and lands in the odor memory there. How can we tell if there is mint in food or if there is another substance? When the compound reaches the brain, the brain displays all the stored smells and identifies this coded compound. Some scientists said that there are 10.000 smells in the brain's memory, and when the brain gets a matching smell, it sends the interpretation to the man and thus the latter will know what the smell in the food is. 

﴾Verily, We created man of the best stature (mould),﴿ 

[At-Tin, 4]

 Remember that this nose has interior nested surfaces, and it has arteries and muscles which expand in the cold weather. Also, there is mucus material in it to catch all dust particles, there are tiny hairs and there is the smell nerve which consists of 20 million nerves each of which ends with 7 cilia, and each one of them is dipped in a mucus substance. These cilia interact with the smells and the outcome is a geometric shape which is the chemical compound of this smell, and this compound moves to the part in the brain that is responsible for smelling where the odor memory is, so the brain displays all the stored smells in order to identify this smell: 

﴾Verily, We created man of the best stature (mould),﴿

[At-Tin, 4]

 When man is forgetful of his Lord:

﴾Then We reduced him to the lowest of the low,﴿

[At-Tin, 5]

Reflecting on your body will lead you to the Creator:

 Dear brother, is there anything closer to you than your own body? Your hair, your nose, your lips, your tongue, your throat, your bronchus, your stomach, your intestines, your pancreas, your liver, your heart, your lungs, your muscles, your brain, your nerves and your spinal cord are but miracles in your miraculous body.

You think you are an insignificant body
while the greatest world is within you

﴾And also in your ownselves. Will you not then see?﴿

[Adh-Dhariyat, 21]

﴾ Verily! In the creation of the heavens and the earth, and in the alternation of night and day, there are indeed signs for men of understanding* Those who remember Allah (always, and in prayers) standing, sitting, and lying down on their sides, and think deeply about the creation of the heavens and the earth, ﴿

[Aal-'Imran, 190-191]
