Musnad Ahmad 2397
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn 'Abbas (رضي الله عنه) said: Two men came to the Prophet of Allah (ﷺ) with the same need. One of them spoke, and the Prophet (ﷺ) noticed a bad smell from his mouth, so he said to him: "Why don't you use the miswak?" He said: I do, but I have not eaten for three days. So he ordered a man to host him and (that man) hosted him and met his needs.
