أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ أَنْبَأَنَا هِشَامٌ، عَنْ يَحْيَى، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، عَنْ أَبِي قَتَادَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا شَرِبَ أَحَدُكُمْ فَلاَ يَتَنَفَّسْ فِي إِنَائِهِ وَإِذَا أَتَى الْخَلاَءَ فَلاَ يَمَسَّ ذَكَرَهُ بِيَمِينِهِ وَلاَ يَتَمَسَّحْ بِيَمِينِهِ ‏"‏ ‏.‏
Translation
It was narrated that Salman said

"The idolators said: 'We see that your companion teaches you how to go to the toilet.' He said: 'Yes, he forbade us from cleaning ourselves with our right hand, and from facing toward the Qiblah, and he said: 'None of you should clean with less than three stones.'"
