The document discusses textual relations in the Quran from the perspectives of early Muslim scholars and modern linguistic theories of coherence and relevance. It covers Zarkashi's theory of explicit and implicit relations between verses. It also examines relations between verses through techniques like parallelism, subject shifts, and invocations.

The conclusion reiterates that the Quran exhibits organic unity through various textual relations.
