Problem: The language of the Quran has been described as "rhymed prose" as it partakes of both poetry and prose; however, this description runs the risk of failing to convey the rhythmic quality of Quranic language, which is more poetic in some parts and more prose-like in others. Rhyme, while found throughout the Quran, is conspicuous in many of the earlier Meccan suras, in which relatively short verses throw the rhyming words into prominence. The effectiveness of such a form is evident for instance in Sura 81, and there can be no doubt that these passages impressed the conscience of the hearers. Frequently a change of rhyme from one set of verses to another signals a change in the subject of discussion. Later sections also preserve this form but the style is more expository.
Which suras in the Quran are particularly rhythmic?
---
Answer:
earlier Meccan suras
