A systematic literature review synthesizes findings from recent studies focused on the daylighting performance in mosque architecture, particularly emphasizing design strategies, methods of evaluation, and the results obtained with respect to daylighting metrics. [PERSON] et al. (2022) set out to assess the sustainability of a mosque design proposal, with a strong emphasis on design features that promote environmental and energy performance. Their method was primarily evaluative, based on design analysis, without an in-depth focus on daylighting metrics [34]. [PERSON] et al. (2021) approached mosque lighting from a historical perspective, detailing the innovations in mosque lighting techniques within Iran, and their methods were largely qualitative, based on historical analyses [35]. In a more quantitative vein, [PERSON] and [PERSON] (2013) examined the daylight performance of a mosque design with a single pendentive dome during the winter solstice, using daylight simulation tools to analyze spatial daylight autonomy (sDA) and annual sunlight exposure (ASE) [36]. [PERSON] et al. (2021) explored effective daylight design strategies in colonial mosques, using case study analysis methods to qualitatively describe the daylighting strategies but not quantifying their performance [37]. [PERSON] and [PERSON] (2020) compared the lighting designs of two mosque typologies in Jeddah, with a focus on the qualitative evaluation of design elements that influence natural light distribution [38]. [PERSON] (2018) narrated the interplay of daylight within sequential spaces of the Sheikh Lotfollah Mosque, applying a descriptive approach without employing empirical daylighting metrics [39]. [PERSON] and [PERSON] (2016) highlighted the significant role of fenestration in mosque designs in Alexandria since the 19 th century to enhance daylight performance, a comparative study of six mosques typologies through the daylight autonomy as an annual daylighting metric [40]. [PERSON] and [PERSON] (2018) sought to link daylight \begin{table}
