Which prophet's people were destroyed by a devastating rain of hardened clay stones (Sijjeel) from the sky, as a severe punishment for their pervasive and unprecedented immoral practices?

Explanation

Prophet Lut (AS) was sent to the people of Sodom and Gomorrah, who were infamous for their sinful homosexual acts and other widespread corruption. Due to their persistent rejection and evil deeds, they were destroyed by a rain of stones, as described in the Quran (e.g., Surah Hud 11:82).
