Ibn 'Abbas reported it on the authority of Maimuana, the wife of the Messenger of Allah (ﷺ), that the Messenger of Allah (ﷺ) took (a piece of goat's) shoulder at her place, and then offered prayer but did not perform ablution.
قَالَ عَمْرٌو وَحَدَّثَنِي بُكَيْرُ بْنُ الأَشَجِّ، عَنْ كُرَيْبٍ، مَوْلَى ابْنِ عَبَّاسٍ عَنْ مَيْمُونَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم أَنَّ النَّبِيَّ صلى الله عليه وسلم أَكَلَ عِنْدَهَا كَتِفًا ثُمَّ صَلَّى وَلَمْ يَتَوَضَّأْ .
Muslim
