عن عائشة أن النبي صلى الله عليه وسلم قال عشر من الفطرة قص الشارب وإعفاء اللحية والسواك والاستنشاق وقص الأظفار وغسل البراجم ونتف الإبط وحلق العانة وانتقاص الماء Aisha reported: The Messenger of Allah, peace and blessings be upon him, said, “Ten acts are part of natural instinct: trimming the moustache, letting the beard grow, using the toothstick, sniffing water into the nose, clipping the nails, washing the knuckles, removing hair from the underarms, shaving the pubic hair, and cleaning the private parts with water.” Mus’ab said, “I forgot the tenth, except that it might be rinsing the mouth.” Source: Ṣaḥīḥ Muslim
