Another and perhaps more important reason was a religious one. But the full and final revelation came through Muhammad, the last of all prophets, and was embodied in the Quran, which completes and supersedes all previous revelations. This is not really a type of script in itself but consists of a text in one of the standard scripts such as naskhi worked into a pattern in which one half is a mirror image of the other. After an inconclusive siege, the Meccans were forced to retire. The Technology of the Medieval Islamic WorldOverviewFor centuries during the European Middle Ages, non-European cultures continued to make progress in science and technology, only marginally affected by Europe's troubles and relative stagnation. Thus the number 323 was expressed like this: The Egyptians actually wrote them from right to left, but they are set down above from left to right to call g attention to the similarities of the systems. Eventually the United Nations negotiated a truce, but fighting became endemic and war broke out again in 1956, 1967, and 1973. Since all government business was by now transacted in Arabic, manuals of correct usage were written for the instruction of non-Arabic speakers who had found government employment. With the approval of the Byzantine emperor, he dispatched scholars to select and bring back to Baghdad Greek scientific manuscripts for translation into Arabic at Bayt al-Hikmah, "the House of Wisdom.". The Islamic Empire established across Persia, the Middle East, Central Asia, North Africa, Iberia and parts of India from the 8th Century onwards made significant contributions towards mathematics. In the meantime, the Mongols, like so many of the peoples who had come into contact with Islam, had begun to embrace it. The basmalah in the thuluth script on the right has been written in the shape of an ostrich. Also referred to as the Tatars and barbarians, they conquered Persia before moving on to Europe with the Khan of Khans, Genghis Khan as their most important leader. His innovations left all enduring imprint on social welfare, taxation, and the financial and administrative fabric of the growing empire. His reign is now the most famous in the annals of the 'Abbasids - partly because of the fictional role given him in The Thousand and One Nights (portions of which probably date from his reign), but also because his reign and those of his immediate successors marked the high point of the 'Abbasid period. The zakah prescribes payments of fixed proportions of a Muslim's possession for the welfare of the community in general and for its needy members in particular, whether Muslims or non-Muslims. Then, in 1482, in a trivial quarrel, the Muslim kingdom split into two hostile factions and, simultaneously, two strong Christian sovereigns, Ferdinand and Isabella, married and merged their kingdoms. At first, most Muslims simply stayed in Spain; cut off from their original roots by time and distance they quite simply had no other place to go. The scholars at Bayt al-Hikmah also contributed to geometry, a study recommended by Ibn Khaldun, the great North African historian, because "it enlightens the intelligence of the man who cultivates it and gives him the habit of thinking exactly." Western penetration also drew the Middle East into the First World War, when the Ottoman Empire sided with (Germany, and Great Britain, in response, encouraged and supported the Arab Revolt against the Turks. The hajj proper must be made between the eighth and thirteenth days of the 12th month - Dhu al-Hijjah - of the Muslim year, but in one sense it begins when a Muslim approaches Mecca, bathes, trims his nails and hair, discards jewelry and headgear, and puts on the ihram dress. The exercise of self-control extends far beyond refraining from food and drink; to make one's fast acceptable to God, one must also refrain from cursing, lying, cheating, and abusing or harming others. Particularly important were the guilds of artisans which often cut across the divisions of religion and location. Once again, however, the Muslims survived their invaders. It was by no means theoretical speculation; many of the dams, reservoirs, and aqueducts constructed at this time throughout the Islamic world still survive. Calligraphy flourished during the Umayyad era in Damascus. Although the Muslims used force when they met resistance they did not compel their enemies to accept Islam. Many also make the sa'y or running, a reenactment of a frantic search for water by Hagar when she and Abraham's son Ishmael were stranded in the valley of Mecca until the Angel Gabriel led them to water in the Well of Zamzam. They were called ghazis, warriors for the faith, and their highest ambition was to die in battle for their adopted religion. In the eighth century, however, they had a more convenient source: the works of Greek scientists stored in libraries in Constantinople and other centers of the Byzantine empire. The last great Umayyad caliph was Hisham, the fourth son of 'Abd al-Malik to succeed to the caliphate. The new mathematical principle on which the Arabic numerals were based greatly simplified arithmetic. To obtain scarce metals the 'Abbasids had to turn elsewhere. Islamic law is thus different from any other legal system; it differs from canon law in that it is not administered by a church hierarchy; in Islam there is nothing that corresponds to a "church" in the Christian sense. Photo: The basmalah ("In the name of God the Merciful the Compassionate" - the opening words of the Quran) is here done in an elaborate thuluth script with the letters joined so that the entire phrase is written without lifting the pen from the paper. This consists of two simple white seamless garments symbolizing a state of purity; in donning it pilgrims make a declaration of pilgrimage and pronounce a devotional utterance called the talbiyah: "Here I am, O God, at Thy Service" - in Arabic the joyous cry "Labbayk!" In addition to enduring the hardships of desert life, he acquired a taste for the rich language so loved by the Arabs, whose speech was their proudest art, and learned the patience and forbearance of the herdsmen, whose life of solitude he first shared and then came to understand and appreciate. This trade was vital; in the central lands of the 'Abbasid empire natural resources such as metals and wood were scarce, and increases in urban populations had outstripped the capacity of the agricultural system to support them. Islam, major world religion promulgated by the Prophet Muhammad in Arabia in the 7th century ce. Nevertheless, the decline continued. For countless millions, consequently, it has been the single most important force in guiding their religious, social, and cultural lives. The Umayyads, however, did manage to achieve a degree of stability, particularly after 'Abd al-Malik ibn Marwan succeeded to the caliphate in 685. The Arab Spring reignited a debate within the Middle East and in academic circles about the universality of human rights and their compatibility, or incompatibility, with culture and religion. If Western influences are important in the Middle East, however, they are by no means paramount. In relentless succession they had retaken Toledo, Cordoba, and Seville. In innumerable, almost indescribable ways, it is also the central fact of Muslim life. There were four persons obviously marked for leadership: Abu Bakr al-Siddiq, who had not only accompanied Muhammad to Medina ten years before, but had been appointed to take the place of the Prophet as leader of public prayer during Muhammad's last illness; 'Umar ibn al-Khattab, an able and trusted Companion of the Prophet; 'Uthman ibn 'Affan, a respected early convert; and 'Ali ibn Abi Talib, Muhammad's cousin and son-in-law.

Because the religious, political, and military achievements of the Islamic period loom so large in the history of the world, the extraordinary cultural, scientific, technological, and commercial achievements are frequently obscured or overlooked. For all that, the Umayyads, during the ninety years of their leadership, rarely shook off their empire's reputation as a mulk - that is, a worldly kingdom - and in the last years of the dynasty their opponents formed a secret organization devoted to pressing the claims to the caliphate put forward by a descendant of al-'Abbas ibn 'Abd al-Muttalib, an uncle of the Prophet. As they grew in importance to the economy these craftsmen eventually organized themselves into mutual-benefit societies which in some ways were similar to later Western guilds and which offered many social services: lodging travelers, engaging in pious works such as caring for orphans, and endowing schools. Although unable to fend off the Crusaders at first - even offering the Crusaders access to Jerusalem if they would come as pilgrims rather than invaders - the Muslims eventually began to mount effective counterattacks. In Muslim regions, in modern times, the faithful - at the sound of the sunset cannon or the call of the muezzin - break their fast, perform voluntary nocturnal worship (tarawih), and throng the streets in moods that are at once festive and, in the spirit of Ramadan, communal. If you want to answer this question, then you have to think about the Crusades from the Muslim's point of view. To Him belongs all that is Western culture spread with Western economic and political control. Islam has given us education with knowledge which has no limits. Later, he consolidated the support of the tribes within the Arabian Peninsula and subsequently funnelled their energies against the powerful empires of the East: the Sassanians in Persia and the Byzantines in Syria, Palestine, and Egypt. Orhan's successor, Murad I, who launched naval attacks upon the Aegean coasts of Europe, established himself on the European shores of the Bosporus, and crushed a Balkan coalition. Al-Razi, for example, was a philosopher and a mathematician as well as a physician and al-Kindi, the first Muslim philosopher to use Aristotelian logic to support Islamic dogma, also wrote on logic, philosophy, geometry, calculation, arithmetic, music, and astronomy. Despite the great body of tradition and law, however the practice of Islam is essentially personal - a direct relationship between individuals and God. Sometime later Muhammad married Khadijah, by whom he had two sons - who did not survive - and four daughters. Only Granada survived. Among many instruments that arrived in Europe through the Middle East are the lute and the rahab, an ancestor of the violin. The fact that the prophet Muhammad had been a merchant made the role of merchants in Islamic society even more important, as there was now increased respect for the position.

They also organized a bureaucracy able to cope with the complex problems of a vast and diverse empire, and made Arabic the language of government. document.write ('
