Sayyidah Aishah (may Allah be pleased with her) relates that Sayyiduna Abd al-Rahman bin Abi Bakr (may Allah be pleased with him) came in with a tooth-stick (miswak) with which he was cleaning his teeth. I said to him: "O Abd al-Rahman, give me this miswak." He gave it to me, and I (trimmed it with my teeth and) chewed it, then gave it to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) cleaned his teeth with it while he (peace and blessings be upon him) was reclining against my chest. This hadith is sahih (authentic) on the condition of Bukhari and Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) would pray two rak'ahs at night, then, having finished, he would use the miswak. This hadith is sahih (authentic) on the condition of Bukhari and Muslim, but the two Shaykhs did not record it.
