91. Surah Ash-Shams (الشمس), the 91st chapter of the Qur'an, is a remarkably poetic and rhetorically brilliant Makkan Surah composed of 15 verses. Its title translates directly to "The Sun", derived from its very first word. This Surah is universally celebrated in Arabic literature for its unique structural design: it features the longest consecutive sequence of cosmic oaths in the entire Qur'an (eleven distinct oaths), which are masterfully compressed to deliver a singular, profound psychological verdict on the nature of the human soul.
