```Class 7 ICSE History and Civics Summary
Before Islam, Arabia was divided into many tribes. Each tribe had its own customs and chief. Tribal wars were common and there was no strong central government.
Mecca was an important trade centre and the Kaaba was a holy place where many idols were kept. Society had many problems like slavery, gambling, drinking and poor treatment of women.
Prophet Muhammad was born in Mecca in 570 CE. He was known for his honesty and kindness. At the age of 40, he received messages from God through Angel Gabriel in the Cave of Hira.
He taught people to believe in one God, Allah, and to treat others with fairness and respect.
People in Mecca opposed Prophet Muhammad. In 622 CE, he moved to Medina. This journey is called Hijrat and marks the beginning of the Islamic calendar.
After Prophet Muhammad's death in 632 CE, Islam spread to Syria, Egypt, Persia and Central Asia through the Caliphs.
Under the Abbasid rulers, Baghdad became one of the greatest cities in the world. It had schools, libraries and centres for learning.
The House of Wisdom in Baghdad became famous for translating books from Greek, Roman and Indian languages into Arabic.
