The Prophet said: "Whoever uses stones to clean himself, let him use an odd number of stones. Whoever does that has done well, and whoever does not, there is no harm in it. Whoever uses a tooth stick should spit out (whatever he removes) and whoever removes (the particle of food) by dislodging it with his tongue should swallow it. Whoever does that has done well, and whoever does not, tere is no harm in it. Whoever goes to the toilet should conceal himself, and if he cannot find anything except a pile of sand (behind which to conceal himself), then he should use that, for the Shaitan plays with the backside of the son of Adam. Whoever does that has done well, and whoever does not, there is no harm in it."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنِ اسْتَجْمَرَ فَلْيُوتِرْ مَنْ فَعَلَ ذَلِكَ فَقَدْ أَحْسَنَ وَمَنْ لاَ فَلاَ حَرَجَ وَمَنْ تَخَلَّلَ فَلْيَلْفِظْ وَمَنْ لاَكَ فَلْيَبْتَلِعْ مَنْ فَعَلَ ذَلِكَ فَقَدْ أَحْسَنَ وَمَنْ لاَ فَلاَ حَرَجَ وَمَنْ أَتَى الْخَلاَءَ فَلْيَسْتَتِرْ فَإِنْ لَمْ يَجِدْ إِلاَّ كَثِيبًا مِنْ رَمْلٍ فَلْيَمْدُدْهُ عَلَيْهِ فَإِنَّ الشَّيْطَانَ يَلْعَبُ بِمَقَاعِدِ ابْنِ آدَمَ مَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَنْ لاَ فَلاَ حَرَجَ  

The Prophet ﷺ said: If anyone applies collyrium, he should do it an odd number of times. If he does so, he has done well; but if not, there is no harm. If anyone cleanses himself with pebbles, he should use an odd number. If he does so, he has done well; but if not, there is no harm. If anyone eats, he should throw away what he removes with a toothpick and swallow what sticks to his tongue. If he does so, he has done well; if not, there is no harm. If anyone goes to relieve himself, he should conceal himself, and if all he can do is to collect a heap of send, he should sit with his back to it, for the devil makes sport with the posteriors of the children of Adam. If he does so, he has done well; but if not, there is no harm. (Using translation from Abū Dāʾūd 35)   

عَنْ أَبِي سَعْدِ الْخَيْرِ وَكَانَ مِنْ أَصْحَابِ عُمَرَ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللهِ ﷺ مَنِ اكْتَحَلَ فَلْيُوتِرْ وَمَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَنْ لَا فَلَا حَرَجَ وَمَنِ اسْتَجْمَرَ فَلْيُوتِرْ وَمَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَنْ لَا فَلَا حَرَجَ وَمَنْ أَكَلَ فَمَا تَخَلَّلَ فَلْيَلْفِظْ وَمَنْ لَاكَ بِلِسَانِهِ فَلْيَبْتَلِعْ مَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَنْ لَا فَلَا حَرَجَ وَمَنْ أَتَى الْغَائِطَ فَلْيَسْتَتِرْ فَإِنْ لَمْ يَجِدْ إِلَّا أَنْ يَجْمَعَ كَثِيبًا فَلْيَسْتَدْبِرْهُ فَإِنَّ الشَّيْطَانَ يَلْعَبُ بِمَقَاعِدِ بَنِي آدَمَ مَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَنْ لَا فَلَا حَرَجَ

قَالَ رَسُولُ اللَّهِ ﷺ «مَنِ اكْتَحَلَ فَلْيُوتِرْ مَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَنْ لَا فَلَا حَرَجَ مَنِ اسْتَجْمَرَ فَلْيُوتِرْ مَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَنْ لَا فَلَا حَرَجَ مَنْ أَكَلَ فَلْيَتَخَلَّلْ فَمَا تَخَلَّلَ فَلْيَلْفِظْ وَمَا لَاكَ بِلِسَانِهِ فَلْيَبْتَلِعْ من فعل ذلك فقد أحسن ومن لا فلا حرج مَنْ أَتَى الْغَائِطَ فَلْيَسْتَتِرْ فَإِنْ لَمْ يَجِدْ إِلَّا كَثِيبَ رَمْلٍ فَلْيَسْتَدْبِرْهُ فَإِنَّ الشَّيَاطِينَ يَتَلَاعَبُونَ بِمَقَاعِدِ بَنِي آدَمَ مَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَنْ لَا فَلَا حَرَجَ»  

"مَنِ اكْتَحَل فَلْيُوتِرْ، مَنْ فَعَلَ فَقَد أَحْسَنَ، وَمَنْ لا، فَلا حَرَجَ، وَمَنْ اسْتَجَمَرَ فَلْيُوتِرْ، مَنْ فَعَل فَقَدَ أَحْسَنَ، وَمَنْ لا، فَلا حَرَجَ، وَمَنْ أَكَلَ فَمَا تَخَلَّلَ فلْيلْفِظ، وَمَنْ لاكَ بِلِسَانِه فَليَبْتَلعْ، مَنْ فَعل فَقَدْ أَحْسَنَ، وَمَنْ لا، فَلا حَرَجَ، وَمَنْ أَتَى الْغَائِطَ فَليَسْتَتِرْ فإِن لَمْ يَجِدْ إِلا أَنْ يَجْمَعَ كَثِيبًا مِنْ رَمْل فَليَسْتَدْبِرْهُ، فَإِنَّ الشَّيطَانَ يَلعَبُ بِمَقَاعِدِ بنى آدَمَ، مَنْ فَعَلَ فَقَدْ أَحْسَنَ وَمَن لا، فَلا حَرَجَ".
