Prophet Musa AS known as Moses in the Hebrew Bible, is considered a prophet, messenger, and leader in Islam.In Islamic tradition instead of introducing a new religion, Moses is regarded by Muslims as teaching and practicing the religion of his predecessors and confirming the scriptures and prophets before him. The Quran states that Moses was sent by God (Arabic: الله‎ Allāh) to the Pharaoh of Egypt and the Israelites for guidance and warning. Moses is mentioned more in the Quran than any other individual, and his life is narrated and recounted more than that of any other prophet.According to Islam, all Muslims must have faith in every prophet (nabi) and messengers (rasul) which includes Moses and his brother Aaron (Harun). Prophet Aaron AS (Arabic: هارون, Hārūn/Haroon) is also mentioned in the Quran as a prophet of God. The Quran praises Aaron repeatedly, calling him a "believing servant" as well as one who was "guided" and one of the "victors". Aaron is important in Islam for his role in the events of the Exodus, in which, according to the Quran and Muslim tradition, he preached with his brother Moses to the Pharaoh of the Exodus. Aaron's significance in Islam, however, is not limited to his role as the helper of Moses. Islamic tradition also accords Aaron the role of a patriarch, as tradition records that the priestly descent came through Aaron's lineage, which included the entire House of Amran. The incident of the Golden Calf as it is narrated in the Qur'an paints Aaron in a positive light. The Qur'an says that Aaron was entrusted the leadership of Israel while Moses was up on Mount Sinai for a period of forty days (Qur'an 7: 142). It adds that Aaron tried his best to stop the worship of the Golden Calf, which was built not by Aaron but by a wicked man by the name of Samiri (Qur'an 19: 50). When Moses returned from Mount Sinai, he rebuked Aaron for allowing the worship of the idol, to which Aaron pleaded with Moses to not blame him when he had no role in its construction (Qur'an 7: 150). The Qur'an then adds that Moses here lamented the sins of Israel and said he only had the power to protect himself and Aaron (Qur'an 5: 25). This book is story about Prophet Moses AS (Musa AS) & Aaron AS (Haroon/Harun AS) in islam religion, based from the Holy Quran & Al-Hadith.
