This study reviews the issue of blasphemy from the perspective of the Qur'an. The main question in this thesis is: how is the interpretation of Qur'anic verses that raise the issue of blasphemy, and how is the concept of blasphemy understood in the context of the Qur'an. The purpose of this study is to illustrate the understanding of Qur'anic verses that discuss blasphemy, as well as to explain the concept of blasphemy according to the perspective of the Qur'an. This research was conducted through library research, by applying thematic methods or maudhu'i. This approach involves collecting data and information from various literature sources relevant to the research theme, such as books of tafsir and other supporting works. From the above it can be concluded that in the Qur'an, the meaning of blasphemy is reflected through the concepts of al-Istihza', al-Sukhriyah, sabba, and syatmun, which indicate acts of degrading and ridiculing others, both through words and actions that are clearly considered blasphemy. The Qur'an affirms that perpetrators of blasphemy are punishable by death. In Indonesia, the punishment is regulated in Article 165a of the Criminal Code which provides criminal sanctions with a maximum prison sentence of 5 years.
