The Messenger of Allah ﷺ said: Ten are the acts according to fitrah (nature): clipping the moustache, letting the beard grow, using the tooth-stick, cleansing the nose (Al-Istinshaq) with water, cutting the nails, washing the finger joints, plucking the hair under the arm-pits, shaving the pubes, and cleansing one's private parts (after easing or urinating) with water. The narrator said: I have forgotten the tenth, but it may have been rinsing the mouth. (Using translation from Abū Dāʾūd 53)   

قَالَ رَسُولُ اللهِ ﷺ عَشْرٌ مِنَ الْفِطْرَةِ قَصُّ الشَّارِبِ وَإِعْفَاءُ اللِّحْيَةِ وَالسِّوَاكُ وَالِاسْتِنْشَاقُ بِالْمَاءِ وَقَصُّ الْأَظْفَارِ وَغَسْلُ الْبَرَاجِمِ وَنَتْفُ الْإِبْطِ وَحَلْقُ الْعَانَةِ وَانْتِقَاصُ الْمَاءِ يَعْنِي الِاسْتِنْجَاءَ بِالْمَاءِ قَالَ زَكَرِيَّا قَالَ مُصْعَبٌ وَنَسِيتُ الْعَاشِرَةَ إِلَّا أَنْ تَكُونَ الْمَضْمَضَةَ  

[Machine] "Indeed, the Prophet ﷺ said: ten things are part of instinctive hygiene: rinsing the mouth, inhaling water into the nostrils, using the tooth stick (Miswak), trimming the mustache, cutting the nails, removing underarm hair, shaving the pubic hair, washing the joints, performing ablution with water, and circumcision."  

أَنَّ النَّبِيَّ ﷺ قَالَ عَشْرٌ مِنَ الْفِطْرَةِ الْمَضْمَضَةُ وَالِاسْتِنْشَاقُ وَالسِّوَاكُ وَقَصُّ الشَّارِبِ وَتَقْلِيمُ الْأَظْفَارِ وَنَتْفُ الْإِبْطِ وَحَلْقُ الْعَانَةِ وَغَسْلُ الْبَرَاجِمِ وَالِانْتِضَاحُ بِالْمَاءِ وَالْخِتَانُ
