Final answer:
The Quran, supplemented by the Hadith and historical context, provided the basis for Quranic reforms, affecting Islamic law, language, and religious practices, while the oral tradition of Quranic recitation remained central to Islamic culture.
Step-by-step explanation:
The basis for Quranic reforms and others would be rooted in the sacred text of Islam known as the Quran, which consists of divine revelations to the Prophet Muhammad and is foundational to Islamic law and practice. Further interpretations, historical context, and additional components such as the Hadith (sayings and actions of the Prophet Muhammad), have also been instrumental in shaping Islamic legal and social reforms. These texts have led to the establishment of laws and rituals such as prayer, fasting, alms-giving, pilgrimage, as well as legal measures and religious polemics during the post-Hijrah period. The emphasis on Quranic recitation, its compilation into a textual format, and the subsequent flourishing of learning traditions such as grammar and poetry further underscore the Quran's centrality in Islamic heritage and its pivotal role in reforms.
Additional reforms included the conventionalization of Arabic as the official language of the Islamic empire, which signaled a wider embrace of Islamic tenets and practices. Notably, the Sharia, a system of Islamic law based on the Quran and Hadith, evolved over generations to solidify the comprehensive religious, social, and legal framework guiding Muslim communities.
