Someone will be glad to check YOUR answers.

Yep. YOU have to figure it out.

It'll be good practice for finding information on the internet.

To answer these questions:

1. The geography and climate of Arabia played a role in discouraging invaders. The vast deserts, including the Rub' al Khali (Empty Quarter) and the harsh arid environment, made it difficult for invaders to sustain their armies and supply lines.

2. Muhammad, the founder of Islam, was born in the city of Mecca, which is located in present-day Saudi Arabia.

3. Muhammad claimed to have received messages from the angel Gabriel, who conveyed divine revelations to him over a period of 23 years. These revelations form the basis of the Islamic faith and are recorded in the Quran.

4. The holy book of Islam is the Quran. Muslims believe it is the word of God as revealed to Muhammad and view it as a guide for all aspects of life, including spiritual, ethical, and legal matters.

5. Muslims are encouraged to give part of their wealth to charity as a religious obligation called Zakat. It is seen as a way to purify their wealth and share their blessings with those in need. Zakat is one of the Five Pillars of Islam, which are the basic acts of worship for Muslims.

6. The Sasanian Persian empire was conquered by the Muslim Arabs during the Islamic conquests in the 7th century. This conquest dramatically changed the political and religious landscape of the region.

7. After the death of Prophet Muhammad, there was disagreement among the early Muslims regarding the succession of leadership. Some believed that the leadership should stay within Muhammad's family, while others believed that it should be based on the consensus of the community. This led to a division in the Muslim community, resulting in the Sunni and Shia branches of Islam.

8. The rapid growth of Muslim cities can be attributed to various factors. One important aspect was the economic prosperity brought about by trade and commerce, facilitated by the expansion of the Islamic empire. Muslim cities became important centers of business, learning, and cultural exchange, attracting people from different regions and contributing to their growth.

9. The introduction of Arabic numerals to Europeans can be attributed to Islamic scholars during the Middle Ages. They preserved and expanded on the knowledge of mathematics, including the decimal numeral system. European scholars eventually adopted and adapted these numerals into their own systems.

10. Islam was brought to India by Muslim traders and conquerors. The initial contact between Islam and the Indian subcontinent occurred through trade routes, and later, the establishment of Islamic empires and kingdoms in the region further spread the religion. Notable figures such as Sufi saints and Muslim missionaries played significant roles in the spread of Islam in India.
