38. Surah Sad (سورة ص) is the 38th chapter of the Quran, containing 88 verses. Named after the single Arabic letter Sād with which it begins, it belongs to a group of Surahs that open with mysterious isolated letters (Huruf al-Muqatta'at). This Surah is a masterclass in psychology, dealing directly with human pride, the nature of arrogance, and the ultimate victory of patience over tyranny.
