حَدَّثَنَا عَبْدُ الرَّزَّاقِ حَدَّثَنَا مَعْمَرٌ عَنْ أَبِي إِسْحَاقَ عَنْ عَلْقَمَةَ بْنِ قَيْسٍ عَنْ ابْنِ مَسْعُودٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَهَبَ لِحَاجَتِهِ فَأَمَرَ ابْنَ مَسْعُودٍ أَنْ يَأْتِيَهُ بِثَلَاثَةِ أَحْجَارٍ فَجَاءَهُ بِحَجَرَيْنِ وَبِرَوْثَةٍ فَأَلْقَى الرَّوْثَةَ وَقَالَ إِنَّهَا رِكْسٌ ائْتِنِي بِحَجَرٍ
مسند امام احمد بن حنبل · Hadith 4299
It was narrated from Ibn Mas'ood that the Prophet (PBUH) went to relieve himself and he instructed Ibn Mas'ood to bring him three stones, and he brought two stones and a piece of dung. He threw away the dung and said: "It is impure, bring me a stone."
