Step-by-step explanation:
The founding lore of Islam is based on the life and teachings of the Prophet Muhammad. According to tradition, Muhammad received revelations from the angel Gabriel, which he recited and his followers wrote down. These words were compiled into the holy book of Islam, the Qur'an, which Muslims believe to be the word of God as recited by Muhammad.
The Qur'an provides the basis for the Islamic faith and serves as a guide for Muslim beliefs and practices. It contains teachings on various aspects of life, morality, and spirituality. The Qur'an is written in Arabic and is divided into 114 suras or chapters, which were organized from longest to shortest after Muhammad's death.
