Imagine you have a toy car and want to share it with your friends. You go to your best friend's house and show them how much fun it is to play with the car. They enjoy playing with it too! Then, they tell their friends about how much fun they had playing with the car, and their friends want to play too. Eventually, everyone in your neighborhood wants to play with the car because they have heard about how great it is to play with.
This is kind of how the spread of Islam happened. Islam started in the Arabian Peninsula with a man named Prophet Muhammad. He told people about the religion and how it could make their lives better. Muhammad's followers, called Muslims, also started to tell their friends and families about Islam. This made more people interested in Islam and wanting to learn more about it.
As Islam spread to different parts of the world, Muslims would teach others about their religion through things like trade, travel, and conquest. They would share their stories and beliefs, and many people found Islam to be appealing because it offered them a sense of community and purpose.
Overall, the spread of Islam was similar to how you would share a toy car with your friends. People learned about Islam from their friends and family who were already practicing it, and they found it to be a fulfilling way of life.
