When we died, and after a few years we will be bones. A few years later the bones and even then will be destroyed and turned into a kind of seed, and in the seed, we will find a very small bones called 'ajbudz dzanab' (coccyx). from that bones we will be resurrected by God Almighty on Judgment Day.
حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ فِي الإِنْسَانِ عَظْمًا لاَ تَأْكُلُهُ الأَرْضُ أَبَدًا فِيهِ يُرَكَّبُ يَوْمَ الْقِيَامَةِ " . قَالُوا أَىُّ عَظْمٍ هُوَ يَا رَسُولَ اللَّهِ قَالَ " عَجْبُ الذَّنَبِ "
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: Allah's Messenger, which bone is that? Thereupon he said: It is the spinal bone.
more than a thousand year ago, the hadith could not be explained by logic. Over time some scientific studies finally can explaining the truth of this hadith. As the technology advances, the function of these organs increasingly revealed. Coccyx supports the bones around the pelvis and is the meeting point of some small muscles. Boneless, humans would not be able to sit comfortably.
A German scientist, Han Spemann, managed to get the Nobel Prize in medicine in 1935. In his research he can prove that the origin of life is the coccyx, from whom the living things originated. In his research he cut the tail bone of reptiles, then implanted into embryonic organizer or organizers.
At the moment the sperm fertilizes the ovum (egg cel), then the formation of the fetus begins. When the ovum has been fertilized (zygotes), it splits into two cells and continue to proliferate. Forming embryonic disk (slab embryo) which has two layers.
The first layer, comprising External epiblast cytotrophoblasts, functioning as food supply of embryo in the uterine wall, and distribute nutrients from the blood and glandular fluid in the uterine wall. and the second layer, Internal Hypoblast which has existed since the formation of the fetus first time. On the 15th day, a simple layer appears on the back of the embryo and it's called primitive node
From this some elements and cel, such as the ectoderm, mesoderm, and endoderm formed. Ectoderm, forming skin and central system. Mesoderm, forming smooth muscle digestive system (digestive), skeletal muscle (skeleton), circulatory system, heart, bones in the genital and urinary system (in addition to the bladder), subcutaneous tissue, lymphatic system and out skin. Meanwhile, Endoderm, forming a layer on the digestive system, the respiratory system, the organs associated with the digestive system (such as the liver and pancreas), bladder, thyroid gland (goiter), and the auditory canal. and this refer to as BONE TAI.
