Dr. Al-Musnad attributed this problem to the reliance on location coordinates at sea level in calculating prayer times, a factor that does not appear to have an effect in flat areas.
He explained that the width of the visible horizon increases proportionally with altitude above the Earth's surface, which keeps the sun's disk visible for a longer time on upper floors compared to those on lower floors.
Time difference
Dr. Al-Musnad pointed out that the time difference is clearly evident in cities with vertical urban expansion, taking Mecca and the Clock Tower, which reaches a height of 601 meters, as a living example of the difference in sunset time by several minutes.
He proposed a practical solution, which consisted of delaying the call to prayer according to the official calendar of the Holy City, thus achieving the ultimate goal of jurisprudential precaution in worship, given the difficulty of setting an independent timing for each floor.
Time differences
He emphasized that the temporary nature of the visitors to these towers, including pilgrims performing Hajj and Umrah, makes it difficult to raise awareness about time differences, thus making a unified solution an urgent necessity to keep pace with urban development in major cities like Riyadh and Jeddah.
