Did the Prophet (Sallallahu Alayhi wa Sallam) share his siwaak with his wives?
The hadith above could mean that the Prophet (sallallahu alaihi wa sallam) used to firstly use the siwaak and then give it to Aisha (Radiyallaahu Anha) to wash to be kept till it is used again. It could also mean that he used to give it to her before using it himself so that she could wash and chew it to make it soft for him to use. (Fat-hul Baari: 2/471; Mirqaatul Mafaatih: 2/96)
