Hadith 5041
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا الْمُعْتَمِرُ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ طَلْقًا، يَذْكُرُ عَشْرَةً مِنَ الْفِطْرَةِ السِّوَاكَ وَقَصَّ الشَّارِبِ وَتَقْلِيمَ الأَظْفَارِ وَغَسْلَ الْبَرَاجِمِ وَحَلْقَ الْعَانَةِ وَالاِسْتِنْشَاقَ . وَأَنَا شَكَكْتُ فِي الْمَضْمَضَةِ .
Al-Mu'tamir narrated that his father said:
"I heard Talq mentioning ten things that have to do with the Fitrah: Using the Siwak, trimming the mustache, clipping the nails, washing the joints, shaving the pubes, rinsing the nose, and I am not sure about rinsing the mouth."
