This may have exerted dominance over the pre-Islamic poets of the 6th century whose popularity may have vied with the Qur'an amongst the people. There was a marked lack of significant poets until the 8th century. One notable exception was Hassan ibn Thabit who wrote poems in praise of Muhammad and was known as the "prophet's poet". Just as the Bible has held an important place in the literature of other languages, The Qur'an is important to Arabic. It is the source of many ideas, allusions and quotes and its moral message informs many works.
