The Temple of the Sun was the chief place of worship of the Inca people in their capital city of Cusco. The Sun God was the chief deity of the Inca people and the Emperor was meant to be revered as a living descendant (or incarnation) of the Sun God.

According to Islamic belief, Mohammed was praying in the mountains one day, in the early seventh century, when he was visited by the angel Gabriel. Gabriel is believed to have passed on the word of God to Mohammed. It was from this divine incident that the religion of Islam would be formed.

The Dar al-Islam is the name given to everywhere in the world that is under the rule of Islamic law. Dar al-Islam literally means Abode of Islam or Home of Islam, and is contrasted against the Dar al-Harb, Abode of War.

After its formation in the sixth century, Islam spread rapidly around North Africa, Central and Southern Asia, and the Middle East. Islam had reached India by the early seventh century.

Islam was founded by the Prophet Muhammad in the seventh century CE. It is an Abrahamic religion, which means it continues the same monotheistic tradition as Judaism and Christianity. Islam spread extremely rapidly around the Middle East and North Africa in the centuries after its foundation.

The Five Pillars of Islam are: Faith - the belief that Allah is the one God and Muhammad is his Prophet; Prayer - the action of praying five times a day in the direction of Mecca; Charity - giving a portion of one’s wealth to the needy; Fasting - the obligation to abstain from eating food during the daylight hours of the month of Ramadan; Pilgrimage - the duty, if one is able, to make a pilgrimage to Mecca at least once in one’s lifetime.

Jerusalem, which is also a holy city to Jewish and Christian people, is an Islamic holy city because it is believed that the Prophet Mohammed ascended to heaven from Jerusalem. The fact that Jerusalem is a holy city in the three largest monotheistic religions in the world has been a source of constant tension and bloodshed for more than one thousand years.

The Dar al-Islam is everywhere in the world where Islam can be practiced freely. It is sometimes defined as everywhere in the world under the rule of Sharia Law, although this definition is less common in contemporary times. All of these countries are predominantly Muslim.

The Holy Inquisition was established in the thirteenth century by Pope Gregory IX. It was established at a time when many heterodox sects of Christianity were emerging in different parts of Europe. The primary purpose of the Holy Inquisition was to find and destroy unorthodox Christian worship (any worship outside the realm of the Catholic church) in Catholic Europe.

Islam arrived in Ghana in the ninth century and many individuals privately converted to the new faith. The state itself, however, did not adopt Islam as its official religion until forced to do so by the invading Almoravid Berbers. Mali, on the other hand, peacefully converted to Islam and benefitted immensely from their relationship with the Islamic world.
