Isma'il bin Ja'far bin Abi Kathir إسماعيل بن جعفر بن أبي كثير الأنصاري · Chapters on Virtues

that the Prophet (ﷺ) said: "People should stop boasting about their fathers who have died, while they are but coals of Hell, or they will be more humiliated with Allah than the dung beetle who rolls dung with his nose. Indeed Allah has removed the pride of Jahiliyyah from you, and its boasting about lineage. from dust."
