Many Islamic legal rulings depend on the reality of sound and light, as they are among the essential pillars upon which human life is based at all times and in all places. This is affirmed in the Qur’an, for life has no meaning without sound or light. This research aims to clarify the concept of sound and light, and to explain the jurisprudential rulings related to each, whether those concerning acts of worship such as prayer, fasting, zakat, and pilgrimage, or those related to matters beyond worship such noise, singing, musical instruments, and entertainment devices. Although sound is absolute in being the means of human interaction, Islamic law has restricted this absoluteness by warning women against raising their voices in places that might expose them to temptation or intrigue in the presence of men. Islam also emphasized the obligation for men to raise their voices in many religious matters, such as the call to prayer (adhān), the iqāmah, and the talbiyah during pilgrimage. At the same time, Islam urged lowering the voice in sacred places for both men and women so as not to disturb others during acts of worship. Furthermore, Islam stressed the duty of respecting neighbors day and night, rendering noise disliked (makrūh), and in some cases, prohibited (harām). Through this study, the significance of light in determining jurisprudential rulings also becomes clear. Allah has linked acts of worship to the light of the sun and the moon, such as the times of prayer, and the beginning and end of lunar months, which are always under the observation of scholars, particularly the sacred months. All of this is addressed in detail within this research, with Allah’s guidance and success. Keywords: (Sound, Light, Adhān, Iqāmah, Noise, Āmīn).
