It was narrated from Umm Salamah that the Messenger of Allah ﷺ at (meat from) a shoulder, then Bilal came to him and he went out to pray, and he did not touch water.  

أَنَّ رَسُولَ اللَّهِ ﷺ أَكَلَ كَتِفًا فَجَاءَهُ بِلاَلٌ فَخَرَجَ إِلَى الصَّلاَةِ وَلَمْ يَمَسَّ مَاءً  

"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'.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصْبِحُ جُنُبًا مِنْ غَيْرِ احْتِلاَمٍ ثُمَّ يَصُومُ وَحَدَّثَنَا مَعَ هَذَا الْحَدِيثِ أَنَّهَا حَدَّثَتْهُ أَنَّهَا قَرَّبَتْ إِلَى النَّبِيِّ ﷺ جَنْبًا مَشْوِيًّا فَأَكَلَ مِنْهُ ثُمَّ قَامَ إِلَى الصَّلاَةِ وَلَمْ يَتَوَضَّأْ  

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. "  

شَهِدْتُ رَسُولَ اللَّهِ ﷺ أَكَلَ خُبْزًا وَلَحْمًا ثُمَّ قَامَ إِلَى الصَّلاَةِ وَلَمْ يَتَوَضَّأْ  

It was reported that Jabir (ra) said "That last of the two matters from the Messenger ofAllah ﷺ was leaving off ablution from that which had been touched by fire."  

كَانَ آخِرَ الأَمْرَيْنِ مِنْ رَسُولِ اللَّهِ ﷺ تَرْكُ الْوُضُوءِ مِمَّا مَسَّتِ النَّارُ
