‘Abdur-Rahman bin Al-Aswad (narrated) from his father that he heard ‘Abdullah say: “The Prophet صلی اللہ علیہ وآلہ وسلم, wanted to defecate, and he told me to bring him three stones. I found two stones and looked for a third, but I could not find any, so I picked up a piece of dung and brought them to the Prophet He took the two stones and threw away the dung and said: “This is Riks.” (Sahih) Abu ‘Abdur-Rahman (An-Nasa’i) said: Riks is the food of the jinn.
