Hadith of the ark
The hadith of the ark (Arabic: حدیث السفینة, romanized: ḥadīth al-safīna) is a saying (hadith) attributed to the Islamic prophet Muhammad that likens his household (Ahl al-Bayt) to Noah's ark; whoever turns to them is saved and whoever turns away from them perishes. Reported by both Shia and Sunni authorities, this hadith is of particular significance in Shia Islam, where the Ahl al-Bayt are viewed as the spiritual and political successors of Muhammad.
