The difference in the mention of "heaven" in the Qur'an, sometimes as singular (samāʼ) and sometimes plural (samāwāt), raises questions because they both have the same meaning, "heaven", without any obvious difference. A contemporary approach proposes that samāʼ refers to the context of a verse that is global, while samāwāt refers to a more detailed context. This study aims to find differences in the use of the two terms in verses that discuss the creation of the sky, with the aim of understanding the meaning of "generality" and "detail" in the creation of the sky. This research uses a literature method by referring to classical and contemporary interpretations, without involving field studies. The results show that when the Qur'an mentions the chronology and duration of the creation of the heavens, the term samāwāt is used, while for general depictions, the term samāʼ is used more frequently, although sometimes samāwāt is also used. The purpose of this research is not only to uncover the implicit meaning in the Qur'an, but also to show the magic of language and science in the text. Thus, this research aims to bridge the gap between religious understanding and modern science, especially in the context of the creation of the sky.
