Early Islamic sources refer to the foundational texts and historical accounts that document the life and teachings of Prophet Muhammad and the development of Islam. These sources include the Qur'an, which is considered the holy book of Islam, and the Hadith, which are collections of sayings and actions of the Prophet. Together, they provide insights into the beliefs, practices, and early community of Muslims. In addition to religious texts, early Islamic sources encompass historical writings by scholars such as Ibn Ishaq and Al-Tabari. These works chronicle the early Islamic period, including the Rashidun Caliphate and the expansion of Islam. They are essential for understanding the historical context and evolution of Islamic thought and practice.
