Sunan Ibn Majah, Book 1, Hadith 528 (In-Book) ⓘ
Zuhri said: "I had dinner with Walid or Abdul-Malik. When the time for prayer came, I got up to perform ablution. Ja'far bin 'Amr bin Umayyah said: 'I bear witness that my father bore witness, that the Messenger of Allah ate food that had been changed by fire, then he performed prayer, and he did not perform ablution.' (Sahih) And 'Ali bin 'Abdullah bin 'Abbas said: 'And I bear witness to similar from my father.'"
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ الدِّمَشْقِيُّ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا الأَوْزَاعِيُّ، حَدَّثَنَا الزُّهْرِيُّ، قَالَ حَضَرْتُ عَشَاءَ الْوَلِيدِ - أَوْ عَبْدِ الْمَلِكِ - فَلَمَّا حَضَرَتِ الصَّلاَةُ قُمْتُ لأَتَوَضَّأَ فَقَالَ جَعْفَرُ بْنُ عَمْرِو بْنِ أُمَيَّةَ أَشْهَدُ عَلَى أَبِي أَنَّهُ شَهِدَ عَلَى رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ أَنَّهُ أَكَلَ طَعَامًا مِمَّا غَيَّرَتِ النَّارُ ثُمَّ صَلَّى وَلَمْ يَتَوَضَّأْ . وَقَالَ عَلِيُّ بْنُ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ وَأَنَا أَشْهَدُ، عَلَى أَبِي بِمِثْلِ ذَلِكَ .
