Muhammad bin Yusuf al-Baykandi محمد بن يوسف البيكندي البخاري · The Book of Purification

"I entered upon Umm Salamah and she told me that the Messenger of Allah (ﷺ) used to wake up in a state of Janabah without having had a wet dream, then he would fast." And she told him that she brought the Prophet (ﷺ) some grilled ribs and he ate from that, then he got up and prayed, and did not perform Wudu'.

It was reported that Ibn 'Abbas said "I witnessed (that) the Messenger of Allah (ﷺ) ate bread and meat, then stood for prayer and did not perform ablution. "
