The Companions of Al-Rass (الرس) are an ancient community mentioned in the Quran in Surah Al-Furqan (25:38) and Surah Qaf (50:12) as a cautionary example of a nation that was destroyed for its disbelief. The term 'Rass' is widely interpreted by classical scholars to mean 'a well,' suggesting they were a people settled around this vital water source. Islamic exegesis, notably in the works of Ibn Kathir, identifies their prophet as Hanzalah ibn Safwan, who they are said to have rejected and ultimately killed by throwing him into a well. While the Quran provides limited details, scholarly interpretations vary on their precise identity and location, with some suggesting they were a remnant of the Thamud tribe or a community in Azerbaijan or Yemen. The story of Al-Rass serves as a powerful Quranic admonition against the rejection of divine guidance and the persecution of prophets, with their fate listed alongside other annihilated nations like 'Ad and Thamud.
