It is narrated from Nu'man bin Bashir that when it was suggested to send police officers to remove corruption from the land, Ka'b al-Ahbar said: "Wait, do not do this, because it is in the Book of Allah that there will be a people called 'Amlah' (police and the like). In their hands will be whips like the tails of cows; they will not even smell the fragrance of Paradise. So do not be the first to send them." Nu'man says they did exactly that. The narrator says: I asked Yahya, "Who are the 'Amlah'?" He replied, "In Iraq, you call them 'Shurti' (policeman)."
