Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "There are four practices from the time of ignorance which people have not abandoned: wailing (over the dead), taunting one another (the narrator is in doubt, perhaps these are the words), taunting one another regarding lineage, saying that rain has been sent down upon us by such-and-such star, and believing in contagion (of disease)—if out of a hundred camels, one camel gets scabies, then who caused the first camel to get scabies?"
