Sayyidah Aisha (RA) reported that the Prophet ﷺ said, “Ten things are instinctive : trimming the moustache, growing the beard, the siwak, rinsing the nose, clipping the nails, washing the back of fingers, plucking hair in the armpit, shaving the pubes, abstersion with 1 water,” Zakariya reported that Mus’ab said, “I have forgotten the tenth except that it should be rinsing the mouth.” [Ahmed 25114,Muslim 261,Abu Dawud 53,Nisai 5055] --------------------------------------------------------------------------------
