Volume 2, Book 13, Number 15:
Narrated ‘Aisha:
AbdurRahman bin Abi Bakr came holding a Siwak with which he was cleaning his teeth. Allah’s
Apostle looked at him. I requested Abdur-Rahman to give the Siwak to me and after he gave it to me
I divided it, chewed it and gave it to Allah’s Apostle. Then he cleaned his teeth with it and (at that
time) he was resting against my chest.
