Muslims made great advances in many different fields, such as geography, physics, chemistry, mathematics, medicine, pharmacology, architecture, linguistics and astronomy. Algebra and the Arabic numerals were introduced to the world by Muslim scholars. The astrolabe, the quadrant, and other navigational devices and maps were developed by Muslim scholars and played an important role in world progress, most notably in Europe's age of exploration.
Muslim scholars studied the ancient cavitations from Greece and Rome to China and India. The works of Aristotle, Ptolemy, Euclid and others were translated into Arabic. Muslim scholars and scientists then added their own creative ideas, discoveries and inventions, and finally transmitted this new knowledge to Europe, leading directly to the Renaissance. Many scientific and medical treatises, having been translated into Latin, were standard text and reference books as late as the 17thand 18th centuries.
Mathematics
It is interesting to note that Islam so strongly urges mankind to study and explore the universe. For example, the Holy Qur'an states:
"We (Allah) will show you (mankind) Our signs/patterns in the horizons/universe and in yourselves until you are convinced
that the revelation is the truth." [Qur'an, 14:53]
This invitation to explore and search made Muslims interested in astronomy, mathematics, chemistry, and the other sciences, and they had a very clear and firm understanding of the correspondences among geometry, mathematics, and astronomy.
The Muslims invented the symbol for zero (The word "cipher" comes from Arabic sifr), and they organized the numbers into the decimal system - base 10. Additionally, they invented the symbol to express an unknown quantity, i.e. variables like x.
The first great Muslim mathematician, Al-Khawarizmi, invented the subject of algebra (al-Jabr), which was further developed by others, most notably Umar Khayyam. Al-Khawarizmi's work, in Latin translation, brought the Arabic numerals along with the mathematics to Europe, through Spain. The word "algorithm" is derived from his name.
Muslim mathematicians excelled also in geometry, as can be seen in their graphic arts, and it was the great Al-Biruni (who excelled also in the fields of natural history, even geology and mineralogy) who established trigonometry as a distinct branch of mathematics. Other Muslim mathematicians made significant progress in number theory.
Medicine
In Islam, the human body is a source of appreciation, as it is created by Almighty Allah (God). How it functions, how to keep it clean and safe, how to prevent diseases from attacking it or cure those diseases, have been important issues for Muslims.
Prophet Muhammad himself urged people to "take medicines for your diseases", as people at that time were reluctant to do so. He also said,
"God created no illness, but established for it a cure, except for old age. When the antidote is applied, the patient will
recover with the permission of God."
This was strong motivation to encourage Muslim scientists to explore, develop, and apply empirical laws. Much attention was given to medicine and public health care. The first hospital was built in Baghdad in 706 AC. The Muslims also used camel caravans as mobile hospitals, which moved from place to place.
Since the religion did not forbid it, Muslim scholars used human cadavers to study anatomy and physiology and to help their students understand how the body functions. This empirical study enabled surgery to develop very quickly.
Al-Razi, known in the West as Rhazes, the famous physician and scientist, (d. 932) was one of the greatest physicians in the world in the Middle Ages. He stressed empirical observation and clinical medicine and was unrivaled as a diagnostician. He also wrote a treatise on hygiene in hospitals. Khalaf Abul-Qasim Al-Zahrawi was a very famous surgeon in the eleventh century, known in Europe for his work, Concessio (Kitab al-Tasrif).
Ibn Sina (d. 1037), better known to the West as Avicenna, was perhaps the greatest physician until the modern era. His famous book, Al-Qanun fi al-Tibb, remained a standard textbook even in Europe, for over 700 years. Ibn Sina's work is still studied and built upon in the East.
Other significant contributions were made in pharmacology, such as Ibn Sina's Kitab al-Shifa' (Book of Healing), and in public health. Every major city in the Islamic world had a number of excellent hospitals, some of them teaching hospitals, and many of them were specialized for particular diseases, including mental and emotional. The Ottomans were particularly noted for their building of hospitals and for the high level of hygiene practiced in them.
Definition
The word ISLAM has a two-fold meaning: peace, and submission to God. This submission requires a fully conscious and willing effort to submit to the one Almighty God. One must consciously and conscientiously give oneself to the service of Allah. This means to act on what Allah enjoins all of us to do (in the Qur'an) and what His beloved Prophet, Muhammad (pbuh) encouraged us to do in his Sunnah (his lifestyle and sayings personifying the Qur'an).
Once we humble ourselves, rid ourselves of our egoism and submit totally to Allah, and to Him exclusively, in faith and in action, we will surely feel peace in our hearts. Establishing peace in our hearts will bring about peace in our external conduct as well.
Islam is careful to remind us that it not a religion to be paid mere lip service; rather it is an all-encompassing way of life that must be practiced continuously for it to be Islam. The Muslim must practice the five pillars of the religion: the declaration of faith in the oneness of Allah and the prophet hood of Muhammad (pbuh), prayer, fasting the month of Ramadan, alms-tax, and the pilgrimage to Makkah; and believe in the six articles of faith: belief in God, the Holy Books, the prophets, the angels, the Day of Judgment and God's decree, whether for good or ill.
There are other injunctions and commandments which concern virtually all facets of one's personal, family and civic life. These include such matters as diet, clothing, personal hygiene, interpersonal relations, business ethics, responsibilities towards parents, spouse and children, marriage, divorce and inheritance, civil and criminal law, fighting in defense of Islam, relations with non-Muslims, and so much more.
Human Rights
Islam has been from its inception very concerned with issues of human rights. Privacy, freedom, dignity and equality are guaranteed in Islam. The holy Qur'an states clearly:
"There is no compulsion in religion."
And there are no reliable reports to confirm the old accusations that when the Muslim armies were expanding into Asia, Africa and Europe the people were put to the sword if they failed to convert to Islam. The best proof is that not only did the Christians, Jews, Zoroastrians and Hindus in those areas not perish or otherwise disappear, they actually flourished as protected minority communities, and many individuals rose to prominent positions in the arts, sciences, even in government.
The lives, property and privacy of all citizens in an Islamic state are considered sacred, whether or not the person is Muslim. Non-Muslims have freedom of worship and the practice of their religions, including their own family law and religious courts. They are obliged to pay a different tax (Jizyah) instead of the Zakah, and the state is obligated to provide both protection and government services. Before the modern era it was extremely rare to find a state or government anywhere in the world that was as solicitous of its minorities and their civil rights as the Islamic states.
In no other religion did women receive such a degree of legal and moral equality and personal respect. Moreover, racism and tribalism are incompatible with Islam, for the Qur'an speaks of human equality in the following terms:
"Mankind! We created you from a single soul, male and female, and made you into nations and tribes, that you may come
to know one another. Truly, the most honored of you in God's sight is the greatest of you in piety."
