Christianity and Islam are the two largest religions in the world and share a historical and traditional connection, with some major theological differences. The two faiths share a common place of origin in the Middle East, and consider themselves to be monotheistic.
The effect of the spread of Islam was an increase in trade. Unlike early Christianity, Muslims were not reluctant to engage in trade and profit; Muhammad himself was a merchant. As new areas were drawn into the orbit of Islamic civilisation, the new religion provided merchants with a safe context for trade. The application of sharia—Islamic law derived from the Koran—ensured a certain measure of uniformity in the application of criminal justice. Sharia law protected commerce and imposed stiff punishments for theft and dishonesty. Muslim jurists called qadis were established to resolve disputes through the application of sharia. Merchants were thus provided with a forum for making complaints and having them resolved in a consistent and systematic way. Trade and travel were not as risky or perilous as before and both thrived with the coming of Islam.

This process may continue and affect even more neighboring states. In fact, it can happen with any law. I`m not all that smart on this subject, and I would paste the link here, but Brainly won`t let me. Hope this helped, if not comment if you have questions
Throughout much of human history, money took the form of precious metals, coins and even raw materials like livestock or vegetables. The inception of paper money ushered in a bold new era—a world in which currency could purchase goods and services despite having no intrinsic value.While early human societies made extensive use of stone, bronze and iron, it was steel that fueled the Industrial Revolution and built modern cities. Evidence of steel tools dates back 4,000 years, but the alloy was not mass-produced until the invention of the Bessemer Process, a technique for creating steel using molten pig iron, in the 1850s.
