Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Four things are from the matters of ignorance, and people will never abandon them: (1) criticizing lineage, (2) wailing over the dead, (3) dealing with the stars, and (4) saying that a camel got scabies, so it gave scabies to all the others—tell me, who gave scabies to the first one?
