None among the human sciences at all, in general, and the natural sciences - of physics, chemistry, astronomy, even mathematics - in particular that uses numerals more extensively than trade, buying and selling commodities, in calculating quantities, weighs, volumes, lengths and prices between sellers and buyers, exporting and importing, yet exchanging.. If such trade was too wide to the international extent, and was a rooted activity that has lasted many centuries through generations; and if such trade has combined along the sea navigation knowledge so that a merchant was a mariner too, and the result of such a complex prolonged activity was prosperity and emergence of civilizations prior Christ, is it, then, conceivable that such a merchant, the traversing of the oceans and the extended desert roads to thousands of kilometers, would learn the numerals and arithmetic from one who is not so?! Ancient Egyptians were worthier than Indians in inventing the ten digits and their place-value system - were not those made by Arabs - as the ancient Egyptian civilization has no counterpart in the Indian subcontinent. Egyptians have achieved an eminent feat in construction and engineering, but that has not necessitated them to invent the numerals and numeration system!
Indians have surpassed Arabs in agriculture and industry, while Arabs were most masterly in trade and arithmetic. That is why The Qor'ann addressed them in Chapter: Alsaff:10, by: [Oh you who believed! Would I guide you to a trade that saves you from painful torture?]. As agriculture, pasture and industry were activities of intangible existence in the Arabs' life by the rule of their desertified environment. In confirmation to this, the trade as a human activity has been mentioned in Qor'ann five times at least; agriculture as a human activity has been mentioned therein twice only; while practicing pasture or industry have not been mentioned at all as human activities. This indirectly indicates the priorities of the four activities in the Arabs' life basically. Needless to say that Mohammad, the Arab of Makkat, has worked with trade in his life more than he did with pasturing.
However, the use's spreading of the numerals of the Arab merchants in that time was by far less than the use's spreading of the alphabet among the common people of whom a few who new reading and writing at first. The use of numerals necessitated conversance with and practicing of an arithmetic science, or dense practice of trade; not as the practice of a herdsman who sells his cattle, or a farmer who sells his products, nor a grocer, but the practice of an exporting importing merchant together, who goes to the country of source where he deals with specialized merchants (mediators), most likely non-producers. Then he goes back with his purchased commodities to resell them to specialized merchants too, not consumers. Cultured Arabs - especially Moslems - know well through Islamic heritage that Othman Ben-Affann, the great Qorashite merchant was (A whole merchant) among the merchants of the Two-Trips-of-Summer-and-Winter.
Well, what was the Arabs' standing in this Activity, and the proof to it? Well, that is what we are going to find a detailed answer thereto a few lines on.
Maritime mercantile activity has - sea-wise and land-wise - connected to the majority of Arabs in their peninsula from the dawn of history. In the early history, starting with 500 BC at least, and from the north of the peninsula, Nabataeans have pioneered land- and sea-trade via the Red Sea at the West; Gerrheans at the East via Arabian Gulf; and Himyarites at the South via Arabian Sea. In the middle history, starting around 250 AD, with the Nabataeans' state and civilization having vanished, Arab maritime merchants continued in the North via Arabian Gulf, and in the South via Arabian Sea. In the late history beginning from around 650 AD - with Islam having come up - Arab maritime merchants became more active via Arabian Gulf and Arabian Sea, and their trade has prevailed in the Mediterranean Sea northward; while their land-trade convoys were still tread the trade roads of the Arabian peninsula in a variety of directions, specially the Hejazi (inhabitants of Hejaz area whose capital is Makkat) convoys.
Throughout the history, Arabs worked at trade between the ancient kingdoms in Asia, Africa and Europe. Most the ancient historians called those merchants by "Arabs", and the contemporary ones did not differ either, who showed convincement to refer to those mariners with "Arabs". The word "Arab" is the name the ancients have heard it from Arabs themselves about themselves; because the words: "Arab", "Arabi", "Orooba (Arabism)" are original derivatives in the Arabic language.
Trade of the Qorashite Arabs in the Two-Trips-of-Summer-and-Winter has represented a transmitter and a publisher of Arabic numerals from the south-most Arabia (Yemen) in winter time, to the north-most (Sham) in summer time.
Qoraish's land-trade convoys to Bahrain (renowned with its pearls) represented one tributary of the transmission and the publishing of the numerals of the Arab merchants to/from Arabian Gulf.
Hence, no surprise that Qor'ann has pointed out to the navigation of people with ships in the sea, to its navigational circumstances and to the people's life with it in numerous verses. Were not Arabs being those maritime merchants, Qor'ann would not have addressed them - initially - with such numerous verses, among which are:
| 1- | {It is in creating the Heavens and the Earth, the opposition of the day and the night, and the ships that run on the sea with avail to people..} Albaqarat:164[البقرة]. |

| 15- | {The two seas are not alike; One is highly fresh and palatable to drink; and the other is intensely salty; from each of which you eat a soft flesh, get out a jewel to wear, and see the ships traversing on it for you to look after his grant, and you maybe thankful (to Him)} Fater:12[فاطِر]. |
