Musannaf Ibn Abi Shaybah 30065 — A man who falsely accuses a whole

Abu Ma'shar said that it is reported from Ibrahim concerning a person who makes one slanderous accusation against an entire group. He said: One prescribed punishment is to be carried out on him. And Qatadah said: It is reported from al-Hasan al-Basri that there is a prescribed punishment on account of each man among them.
