To understand a text, it is easier to pay attention to the grammatical elements contained therein first, so it is necessary to interpret an element that discusses the harmony and attachment of structural relationships between one utterance and another. Among them is the usage of grammatical cohesion, because it is related to the meaning that will be produced in a discourse. Which are usually marked with, references, substitutions, ellipsis and conjunctions. Therefore this study will review the grammatical cohesion in the Surah Luqman.
