Hadith 1

three for the coccyx. Rather, it was created solid, so that a human would have independence and strength, and be able to move to the directions, and for this reason the joints between them were made not chained, so that the stature would weaken and not be tight, thus preventing turning. And some of them have appendages from above and from below, with them the connection between them is arranged articulated with mortises in some of them, and apical heads in some, and some of them have appendages of another type, broad, solid, placed along their length for protection and a shield and comparison of what is joined and because bonds are woven on them. Whatever of it was laid to the back, it was called thorns and thorns, and what was on the right and left are called wings, and each wing of the ribs had two pits. For each rib, two convex appendages are recessed into the fovea and are connected by strong ligaments. The vertebrae, other than the median foramen, have other holes through which nerves exit and veins enter. And the neck and its vertebrae are protection for the oesophagus and the trachea of the lung, and since the backbone beneath them supports its vertebrae, they must be smaller, and since they are a pathway to the origin of the marrow and its beginning, which must be thicker and greater like the beginning of a river. The median hole of it must be wider, the smallness, and the capacity of the cavity, which eases its offense and weakens it, so the Creator, the Glorious, Corrected this by limiting it to an increase in hardness and protection, not to what is beneath it. He-azwj Made its tooth smaller so that it was lighter for it, then Corrected the smallness of its tooth by Making its wings larger and making it two-headed. And since the neck has the most benefits in its movements, he made its joints smooth and did not make its articular appendages as many as the appendages below it, so that its movements would be faster, and that smoothness would be corrected by the many nerves and muscles surrounding it. And he also made the nerve as pathways that branch off from the medulla joint from two vertebrae so that a complete hole in one vertebra would not fall and weaken it. The backbone and its vertebrae are a protection and a shield for the honourable organs placed in front of it, and for this reason, thorns and spikes were created for it, and it is built for the totality of the bones of the body like the plank that was first prepared in a ship’s keel. Then it is concentrated in it and attached to it the rest of the wood, and for this it was created solid, and it is like one thing specific to the best shapes, and it is the round, as this shape is the furthest from the shapes from accepting the afflictions of collisions (cracks). And since the backbone may require a movement of flexion and curvature towards the two sides, and that is by moving the middle to the opposite side, and what is above and below it inclines towards that side. And the two ends of the back were inclined to meet. It was not created for the vertebra, which is the middle in length and is the tenth of the lobes, but rather a mortise. Then the inferior and superior condyles were directed towards it, while the upper and lower condyles were descending. And as for the lower ascending, to facilitate its removal against the direction of the inclination, and the upper and lower condyles would be pulled to Down and inferior to be pulled up. As for the marrow, it is a white, soft, creamy cerebral body that originates at the back of the brain, as we have mentioned, and it is its successor, from which nerves and muscles are distributed among the organs to benefit them with sense and movement. For the whole of it arises from thirty-one pairs of nerves, and one individual has no equal for it. The first pair emerges from the hole in the first vertebra of the neck vertebra and ascends until it separates in
