The gaze, or the act of seeing the other and the awareness of being seen, has a storied history in the Islamic tradition. In the Qurʾān, the gaze or glance (naẓar), along with the “amorous eye” and its attendant curiosity, is associated with the “lust of the eye” and its corruption of the heart. The indulgence of the concupiscent gaze is most often also presented as the first inauspicious step toward perpetrating the grave sins of fornication or adultery. The Qurʾān instructs the believing men and women to avert their gaze from those of the opposite sex in order to preserve their chastity and thereby ensure their salvation. This thematic study examines the exegetical literature (tafsīr) on Qurʾān 24:30–31 and the concomitant Muḥammadan traditions, or exegetical ḥadīṯ, on the gaze as concupiscent curiosity in medieval Sunnī Islam.
