Respect your elders and ancestors

This hadith is about the importance of the Quraish in Islamic history. It was narrated by Ibn 'Umar, who was a companion of Prophet Muhammad (PBUH). According to this hadith, even if only two members of the Quraish were left alive, they would still have authority over matters related to caliphate. This shows how important and influential this tribe was in early Islamic history. It also serves as a reminder for Muslims to respect their elders and ancestors, no matter how few they may be in number.
