Muhammad ibn al-Muthanna and Ibn Bashshar narrated to us, both saying: 'Abd al-Rahman narrated to us, from Sufyan, from Mansur, and Husayn, and al-A'mash, from Abu Wa'il, from Hudhayfah, that when the Messenger of Allah (peace and blessings of Allah be upon him) rose at night, he would clean his mouth with the toothstick (siwak).
