Ten human urges are from the fitrah (natural human instinct or disposition)
The Messenger of Allah ﷺ said, "Ten are the acts according to fitra: (1) clipping the mustache, (2) letting the beard grow, (3) using the siwāk/miswāk (toothstick), (4) snuffing water in the nose ˹for cleaning˺, (5) cutting the nails, (6) washing the finger joints, (7) plucking the hair under the armpits, (8) shaving the pubic hair, and (9) cleaning one's private parts with water.
The narrator said: I have forgotten the tenth, but it may have been (10) rinsing the mouth.
قَالَ رَسُولُ اللَّهِ ﷺ «عَشْرٌ مِنَ الْفِطْرَةِ: (١) قَصُّ الشَّارِبِ (٢) وَإِعْفَاءُ اللِّحْيَةِ (٣) وَالسِّوَاكُ (٤) وَاسْتِنْشَاقُ الْمَاءِ (٥) وَقَصُّ الأَظْفَارِ (٦) وَغَسْلُ الْبَرَاجِمِ (٧) وَنَتْفُ الإِبْطِ (٨) وَحَلْقُ الْعَانَةِ (٩) وَانْتِقَاصُ الْمَاءِ۔»
قَالَ زَكَرِيَّاءُ قَالَ مُصْعَبٌ وَنَسِيتُ الْعَاشِرَةَ إِلاَّ أَنْ تَكُونَ (١٠) الْمَضْمَضَةَ
