Narrated by:`Aisha
Narrated `Aisha:The Prophet (ﷺ) in his ailment in which he died, used to say, "O `Aisha! I still feel the pain caused by the food I ate at Khaibar, and at this time, I feel as if my aorta is being cut from that poison."
وَقَالَ يُونُسُ عَنِ الزُّهْرِيِّ، قَالَ عُرْوَةُ قَالَتْ عَائِشَةُ ـ رضى الله عنها ـ كَانَ النَّبِيُّ صلى الله عليه وسلم يَقُولُ فِي مَرَضِهِ الَّذِي مَاتَ فِيهِ " يَا عَائِشَةُ مَا أَزَالُ أَجِدُ أَلَمَ الطَّعَامِ الَّذِي أَكَلْتُ بِخَيْبَرَ، فَهَذَا أَوَانُ وَجَدْتُ انْقِطَاعَ أَبْهَرِي مِنْ ذَلِكَ السَّمِّ ".
