Sahih al-Bukhari, Hadith 5404 ⓘ
Narrated Ibn 'Abbas: The Prophet ate of the meat of a shoulder (by cutting the meat with his teeth), and then got up and offered the prayer without performing the ablution anew.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الْوَهَّابِ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا أَيُّوبُ، عَنْ مُحَمَّدٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ تَعَرَّقَ رَسُولُ اللَّهِ صلى الله عليه وسلم كَتِفًا، ثُمَّ قَامَ فَصَلَّى، وَلَمْ يَتَوَضَّأْ.
