Mishkat al-Masabih 379, 380
‘A'isha reported God’s messenger as saying, “Ten characteristics belong to the religion of Islam:
clipping the moustache, letting the beard grow, using the tooth-stick, snuffing up water, cutting the nails, washing the finger joints, plucking the hair under the armpits, shaving the pubes, and intiqas , i.e. cleansing oneself with water.” The narrator said, “I have forgotten the tenth, but it may have been rinsing the mouth.” 

Muslim transmitted it. A version substitutes circumcision for letting the beard grow. I have not found this version in the two Sahihs or in al-Humaidi’s book [ Al-jam’ bain as-sahihain ], but the author of the Jami‘ [Ibn al-Athir, author of Jami' al-usul ]
mentioned it. as did al-Khattabi in Ma'alim as-sunan * from Abu Dawud by the transmission of ‘Ammar b. Yasir.
*Brockelmann, Geschichte ae arabischen Litteratur , Supp., I, 267, 275, calls this work Ma'alim as-sunna , but the title given above is more likely to be correct, as it is a commentary on Abu Dawud’s Sunan .
وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: قَالَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " عَشْرَ مِنَ الْفِطْرَةِ: قَصُّ الشَّارِبِ وَإِعْفَاءُ اللِّحْيَةِ وَالسِّوَاكُ وَاسْتِنْشَاقُ الْمَاءِ وَقَصُّ الْأَظْفَارِ وَغَسْلُ الْبَرَاجِمِ وَنَتْفُ الْإِبِطِ وَحَلْقُ الْعَانَةِ وَانْتِقَاصُ الْمَاءِ)
يَعْنِي الِاسْتِنْجَاءَ - قَالَ الرَّاوِي: ونسيت الْعَاشِرَة إِلَّا أَن تكون الْمَضْمَضَة. رَوَاهُ مُسلم
وَفِي رِوَايَةٍ «الْخِتَانُ» بَدَلَ «إِعْفَاءُ اللِّحْيَةِ» لَمْ أَجِدْ هَذِهِ الرِّوَايَةَ فِي «الصَّحِيحَيْنِ» وَلَا فِي كِتَابِ الْحُمَيْدِيِّ
وَلَكِنْ ذَكَرَهَا صَاحِبُ «الْجَامِعِ» وَكَذَا الْخطابِيّ فِي «معالم السّنَن» :
