Verses 15–19 contain a story about the eponymous people of Sheba. The story is based on the ancient Sabaeans who lived in the central lowlands of Yemen. According to the verses, they were originally prosperous, but turned away from worshiping and giving thanks to God, and as a result suffered a flood. The story is presented as a warning against worldly pride and arrogance. Semitic philologist A. F. L. Beeston linked the story to the prosperous Sabeans of the Ma'rib oasis who settled on each side of the wadi (hence the reference to "the garden of the right" and "of the left" in verse 15. Beeston, CNRS researcher Jérémie Schiettecatte, as well as the Quranic commentary "The Study Quran" argued that the flood corresponds to the failure of the dam system that irrigated the community. The dams were mentioned in inscriptions dated from around 450–540 CE, and "The Study Quran" further argues that the phrase "the flood of 'Arim" correspond to the triliteral root ʿ-r-m that appeared in the inscriptions to refer to the dam system.
