How did Islamic law develop?

Answer 1

The rise of Islam started with the message that was spread by the Prophet Mohammad. After his death the companions who accompanied him through his journey realized the potential danger in losing the message of Islam and the teachings of the Prophet so they set to jot down the revealed knowledge and verses (collectively known as the "Quran"). this move helped preserve the message of islam. during the expansion of the Islamic state the Quran reached many regions of the world, which had slightly different understanding of its contents and thus had different interpretations. this led to the manifestation of different schools of thought and the development of law through their teachings as applied by the rulers of the land.
