The Prophet ﷺ was asked, "Who is the most noble of people?"He replied, "The most God-fearing among them."They said, "That is not what we are asking you about."He said, "Then it is Yusuf, the prophet of Allah, son of the prophet of Allah, son of the prophet of Allah, son of the friend of Allah."They said, "That is not what we are asking you about."He said, "Are you asking me about the noble lineages of the Arabs? The best of them in the days of ignorance are the best of them in Islam, provided they gain understanding of the religion."
قيل للنبي: من أكرم الناس؟ قال: أتقاهم قالوا: ليس عن هذا نسألك؟ قال: فيوسف نبي الله ابن نبي الله ابن نبي الله ابن خليل الله قالوا: ليس عن هذا نسألك قال: فعن معادن العرب تسألوني؟ خيارهم في الجاهلية خيارهم في الإسلام إذا فقهوا.
Bukhari narrated it in the Book of Prophets (3353), and Muslim in the Book of Virtues (2378), both of them through the route of Ubaydullah, who said, Saeed bin Abu Saeed told me, from his father, from Abu Hurairah, who mentioned it.
