Muwatta Malik #49
Purity
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، . أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَكَلَ كَتِفَ شَاةٍ ثُمَّ صَلَّى وَلَمْ يَتَوَضَّأْ .
Yahya related to me from Malik from Zayd Aslam from Ata ibn Yasar
from Abdullah Abbas that the Messenger of Allah, may Allah bless him
and grant him peace, ate a shoulder of lamb and then prayed without
doing wudu.
