Hadith 5421
حَدَّثَنَا هُدْبَةُ بْنُ خَالِدٍ ، حَدَّثَنَا هَمَّامُ بْنُ يَحْيَى ، عَنْ قَتَادَةَ ، قَالَ : كُنَّا نَأْتِي أَنَسَ بْنَ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ وَخَبَّازُهُ قَائِمٌ ، قَالَ : " كُلُوا فَمَا أَعْلَمُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى رَغِيفًا مُرَقَّقًا حَتَّى لَحِقَ بِاللَّهِ وَلَا رَأَى شَاةً سَمِيطًا بِعَيْنِهِ قَطُّ " .
Narrated Qatada: We used to visit Anas bin Malik while his baker was standing (and baking). Anas would say, "Eat! I do not know that the Prophet had ever seen well-baked bread till he met Allah, nor had he ever seen a roasted sheep with his own eyes."

حَدَّثَنَا مُحَمَّدُ بْنُ مُقَاتِلٍ ، أَخْبَرَنَا عَبْدُ اللَّهِ ، أَخْبَرَنَا مَعْمَرٌ ، عَنْ الزُّهْرِيِّ ، عَنْ جَعْفَرِ بْنِ عَمْرِو بْنِ أُمَيَّةَ الضَّمْرِيِّ ، عَنْ أَبِيهِ ، قَالَ : " رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَحْتَزُّ مِنْ كَتِفِ شَاةٍ فَأَكَلَ مِنْهَا ، فَدُعِيَ إِلَى الصَّلَاةِ ، فَقَامَ فَطَرَحَ السِّكِّينَ فَصَلَّى وَلَمْ يَتَوَضَّأْ " .
Narrated `Amr bin Umaiyay Ad-Damri: I saw Allah's Apostle cutting part of the shoulder of mutton with a knife. He ate of it and then was called for prayer whereupon he got up and put down the knife and offered the prayer without performing new ablution.
