The whole body decays except the coccyx ,

 
Scientific miracle in the sunnah :

The whole body decays except the coccyx ,

In a number of Prophetic Hadeeths, the Prophet, sallallaahu ‘alayhi wa sallam, mentioned that the tailbone is a small bone at the base of the spinal column. It is a remnant of the primary strand from which the human body is created in the embryonic stage, and it remains after his death and even after his body decomposes. It is this coccyx from which man will be brought back to life on the Day of Resurrection.


The Prophet, sallallaahu ‘alayhi wa sallam, asserted that Allaah The Almighty will send rain from the sky and then the dead bodies will grow from these coccyges like vegetation grows.
According to another narration of Muslim: “There is a bone in the
human being which the earth would never consume and it is from this that new bodies would be reconstituted (on the Day of Resurrection). They said, ‘O Messenger of Allaah, which bone is that?’ Thereupon, he said: ‘It is the tailbone.’”
In a third narration of Muslim on the authority of Abu Hurayrah, may Allaah be pleased with him, the Prophet, sallallaahu ‘alayhi wa sallam, said:
“‘Between the two times of blowing of the trumpet there would be
(an interval of) forty. They said, ‘O Abu Hurayrah, do you mean
forty days?’ He said, ‘I refuse to answer .’ They said, ‘Do you
mean forty months?’ He said, ‘I refuse to answer.’ They said, ‘Do
you mean forty years?’ He said, ‘I refuse to answer. Then Allaah
would cause water to descend from the sky and they (people) will
sprout like vegetables. The earth would consume every part of the
son of Aadam (after his death) except for one bone; the coccyx
(the bone at the base of the vertebral column) from which he is
created and from which his body will be reconstituted on the Day
of Resurrection .’”
The Prophet, sallallaahu ‘alayhi wa sallam, foretold a scientific fact that was only discovered a few years ago. Specialists in embryology have proven that the human body is created from a very delicate strand called "the primary strand.” This is created, with the will of Allaah The Almighty on the 15th day of the fertilization of the ovum and its implantation in the wall of the uterus. When this strand is found, all the organs of the embryo start to be formed, especially the nervous system,
the initial parts of the vertebral column and the rest of the body parts because Allaah has given this strand the ability to stimulate the cells to start to divide, differentiate from each other and acquire their own specific characteristics. It also helps them accumulate together in their specialized tissues and full organs, which complement each other in their cooperation to perform all bodily functions.
It has been proven that this preliminary strand decomposes (after man's death) except for a small part (the origin of the coccyx), which remains at the end of the vertebral column (or in the vertebra known as the coccyx) and this is what is meant by "‘Ajbu Ath-Thanab" in the Hadeeths of the Prophet, sallallaahu ‘alayhi wa sallam. When man dies, the whole body decomposes except for this part, from which – as mentioned in the Hadeeth – man will be recreated exactly as a plant germinates from a seed. This process will take place, when, at the time of Resurrection,
special rain will fall from the sky, by the will of Allaah The Almighty.
A group of Chinese scientists proved in some of their laboratory
experiments that it is impossible for this part, the end part of the coccyx, to be destroyed completely. They tried to dissolve it chemically in the strongest acids, through burning, crushing, and by subjecting it to various types of radiation. This definitely proves that the Hadeeth of the Prophet, sallallaahu ‘alayhi wa sallam, is true and precedes all scientific experiments by 1400 years at least.
