Hadith 754
Sayyiduna Abu Hurairah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "When the Day of Resurrection comes, by Allah's command, a caller will announce: I established lineage and you also established lineage, so I made the most pious among you the most honorable, but you refused except to say: So-and-so son of so-and-so is better than so-and-so son of so-and-so. So today I will elevate My lineage and lower your lineage. Where are the pious people?"
