"When I looked at the science of engineering and saw that it had disappeared after its ancient heritage, that its masters have perished, and that their memories are now forgotten, I worked my wits and thoughts in secrecy about philosophical shapes and figures, which could move the mind, with effort, from nothingness to being and from idleness to motion. And I arranged these shapes one by one in drawings and explained them."

"It is impossible to over-emphasize the importance of al-Jazari's work in the history of engineering. Until modern times there is no other document from any cultural area that provides a comparable wealth of instructions for the design, manufacture and assembly of machines… Al-Jazari did not only assimilate the techniques of his non-Arab and Arab predecessors, he was also creative. He added several mechanical and hydraulic devices. The impact of these inventions can be seen in the later designing of steam engines and internal combustion engines, paving the way for automatic control and other modern machinery. The impact of al-Jazari's inventions is still felt in modern contemporary mechanical engineering [2].""
"The Indians, as known to all nations for many centuries, are the metal [essence] of wisdom, the source of fairness and objectivity. They are peoples of sublime pensiveness, universal apologues, and useful and rare inventions. In spite of the fact that their color is in the first stage of blackness, which puts them in the same category as the blacks, Allah, in His glory, did not give them the low characters, the poor manners, or the inferior principles associated with this group and ranked them above a large number of white and brown peoples."
"The first nation (to have cultivated science) is India. This is a powerful nation having a large population, and a rich kingdom (possession). India is known for the wisdom of its people. Over many centuries, all the kings of the past have recognized the ability of the Indians in all the branches of knowledge."
"The kings of China have stated that the kings of the world are five in number and all the people of the world are their subjects. They mentioned the king of China, the king of India, the king of the Turks, the king of the Furs (Persians) and the king of the Romans (1). They referred to the king of China as the "king of humans" because the people of China are more obedient to authority and are stronger followers of government policies than all the other peoples of the world. They referred to the king of India as the "king of wisdom" because of the Indians careful treatment of `ul?m (sciences) and their advancement in all the branches of knowledge. They referred to the king of the Turks as the "king of lions" because of the courage and the ferocity of the Turks. They referred to the king of Persia as the "king of kings" because of the richness, glory and importance of his kingdom, since Persia had subdued the kings of the center of the populated world, and because it controlled, to the exclusion of other kingdoms, the most fertile of the climatic regions. And they referred to the king of the Romans as the "king of men" because the Romans, of all the peoples, have the most beautiful faces, the best built bodies and the most robust physique."
"Some astrologers came up with an explanation for this condition; they said that both Saturn and Mercury control the destiny of the Indian people. Because of the influence of Saturn, their color turned black, while the influence of Mercury provided them with intellectual power and fine spirit. Saturn in partnership with Mercury gave them correctness of reasoning and depth of perception. This is why they enjoy the purity of talent and the power of distinction, making them totally different from the people of Sudan (Blacks) (2) such as the Zinj, the Abyssinians, the Ethiopians and others. To their credit, the Indians have made great strides in the study of numbers (3) and of geometry. They have acquired immense information and reached the zenith in their knowledge of the movements of the stars (astronomy) and the secrets of the skies (astrology) as well as other mathematical studies. After all that, they have surpassed all the other peoples in their knowledge of medical science and the strengths of various drugs, the characteristics of compounds and the peculiarities of substances."
"That which has reached us from the discoveries of their clear thinking and the marvels of their inventions is the (game) of chess. The Indians have, in the construction of its cells, its double numbers, its symbols and secrets, reached the forefront of knowledge. They have extracted its mysteries from supernatural forces. While the game is being played and its pieces are being maneuvered, there appear the beauty of structure and the greatness of harmony. It demonstrates the manifestation of high intentions and noble deeds, as it provides various forms of warnings from enemies and points out ruses as well as ways to avoid dangers. And in this, there is considerable gain and useful profit."
"We should not be ashamed to acknowledge truth from whatever source it comes to us, even if it is brought to us by former generations and foreign peoples. For him who seeks the truth there is nothing of higher value than truth itself."
"We ought not to be ashamed of appreciating the truth and of acquiring it wherever it comes from, even if it comes from races distant and nations different from us. For the seeker of truth nothing takes precedence over the truth."
