Modern Islam retains strong Arabic, Persian, and Turkish influences. The official language of the Qu'ran is standard Arabic, a regional tongue shared by diverse communities across the Arabian peninsula. The strong literary and poetic emphasis is due in part to the influence of Persian scholars and monks. In addition to such cultural influences, Islam also grew in opposition to local custom and tradition. Many Islamic precepts were specifically designed to separate Muslims from those who worshipped native gods. For example, the instruction against creating images of the Divine is rooted in a historical attempt to demarcate Muslim worship from indigenous ritual, in which participants regularly made use of images of the gods. Similarly, the religious regulation of commerce, marriage, politics and domestic life were heavily influenced by early Muslims' strong desire to create a lifestyle and community distinct from those of their polytheistic neighbors.
