This study examines the verses in the Qur’ān concerning angels by adhering to the chronological order of revelation. In doing so, it seeks to trace the historical development of the Qur’ānic angelology and to analyze the functional diversity attributed to angels within the Qur’ānic discourse. Although belief in angels constitutes one of the fundamental tenets of Islamic theology, it has often been approached through systematic and speculative frameworks in classical Kalām literature. Such approaches, while valuable, tend to overlook the revelational context and the chronological engagement of the Qur’ān with its initial audience. Accordingly, this study aims to uncover the revelational basis upon which classical theological doctrines were constructed by returning to the primary Qur’ānic data, and to contextualize the evolving concept of angels within the process of revelation itself. The study classifies the verses pertaining to angels based on the chronological order of the surahs and employs a thematic methodology. It also considers the historical and sociocultural context of the revelations and benefits from both classical and contemporary exegetical sources to present a holistic analysis. It is observed that angels in the Qur’ān are not only described as metaphysical beings, but also as agents tasked with transmitting revelation, recording deeds, delivering glad tidings or punishment, and even administering death. In the Qur’ān, the word malak (angel) appears a total of 87 times in singular, dual, and plural forms. Of these occurrences, 15 are in the singular form, 2 in the dual, and the remaining 70 in the plural form. Additionally, when considering the verses in which angels are mentioned indirectly, various references to angels can be found in a total of 193 verses throughout the Qur’ān. According to scholarly findings, 155 of these 193 verses belong to the Meccan period of revelation, while 38 are from the Medinan period. Moreover, Meccan verses prominently feature themes such as the Day of Judgment, Hell, the Hereafter, the prostration of the angels before Adam and the refusal of Iblis to do so, the polytheists’ claim that angels are the daughters of Allah, and their demand to visibly witness the angels. In contrast, Medinan verses emphasize belief in angels, the rejection of their deification, and references to angels in numerical compositions. Furthermore, the article explores several frequently repeated themes that underscore the centrality of angels in the Qur’ānic worldview and Islamic theological framework. These include: the seven distinct instances of angels prostrating before Adam; the various numerical constructions associated with angels; theological and exegetical debates surrounding the true nature of Hārūt and Mārūt; the recurring question of whether Iblīs was one of the angels; and the multiple occasions in which disbelieving communities questioned the Prophet’s humanity or demanded an accompanying angel. Taking all these elements into consideration, the study concludes that the belief in angels is not merely one of the articles of faith, but also a vital metaphysical and moral component through which the Qur’ān addresses, educates, and spiritually disciplines its audience.
