The Prophet ﷺ went out to answer the call of nature and asked me to bring three stones. I found two stones and searched for the third but could not find it. So took a dried piece of dung and brought it to him. He took the two stones and threw away the dung and said, "This is a filthy thing."  

أَنَّهُ سَمِعَ عَبْدَ اللَّهِ يَقُولُ أَتَى النَّبِيُّ ﷺ الْغَائِطَ فَأَمَرَنِي أَنْ آتِيَهُ بِثَلاَثَةِ أَحْجَارٍ فَوَجَدْتُ حَجَرَيْنِ وَالْتَمَسْتُ الثَّالِثَ فَلَمْ أَجِدْهُ فَأَخَذْتُ رَوْثَةً فَأَتَيْتُهُ بِهَا فَأَخَذَ الْحَجَرَيْنِ وَأَلْقَى الرَّوْثَةَ وَقَالَ هَذَا رِكْسٌ وَقَالَ إِبْرَاهِيمُ بْنُ يُوسُفَ عَنْ أَبِيهِ عَنْ أَبِي إِسْحَاقَ حَدَّثَنِي عَبْدُ الرَّحْمَنِ  

"The Prophet ﷺ 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 ﷺ. He took the two stones and three away the dung and said: "This is Riks." Abu 'Abdur-Rahman (An-Nasai') said: Riks is the food of the jinn. (Using translation from Nasāʾī 42)   

أَنَّهُ سَمِعَ عَبْدَ اللهِ بْنَ مَسْعُودٍ يَقُولُ أَتَى النَّبِيُّ ﷺ الْغَائِطَ وَأَمَرَنِي أَنْ آتِيَهُ بِثَلَاثَةِ أَحْجَارٍ فَوَجَدْتُ حَجَرَيْنِ وَلَمْ أَجِدِ الثَّالِثَ فَأَخَذْتُ رَوْثَةً فَأَتَيْتُ بِهِنَّ النَّبِيَّ ﷺ فَأَخَذَ الْحَجَرَيْنِ وَأَلْقَى الرَّوْثَةَ وَقَالَ هَذِهِ رِكْسٌ  

"The Messenger of Allah went to the toilet and said: 'Bring me three stones.' So I brought him two stones and a piece of dung. He took the two stones and threw the dung away, saying: 'It is impure.'" (Using translation from Ibn Mājah 314)   

أَنَّ رَسُولَ اللهِ ﷺ أَتَى الْخَلَاءَ وَقَالَ ائْتِنِي بِثَلَاثَةِ أَحْجَارٍ فَالْتَمَسْتُ فَوَجَدْتُ حَجَرَيْنِ وَلَمْ أَجِدِ الثَّالِثَ فَأَتَيْتُهُ بِحَجَرَيْنِ وَرَوْثَةٍ فَأَخَذَ الْحَجَرَيْنِ وَأَلْقَى الرَّوْثَةَ وَقَالَ إِنَّهَا رِكْسٌ
