Narrated Khalid bin Al-Walid: "A roasted mastigure was brought to the Prophet (ﷺ) who stretched his hand towards it to eat it. But it was said to him, "It is a mastigure." So he withdrew his hand. Khalid asked, "Is it unlawful to eat?" the Prophet said, "No, but it is not found in the land of my people and that is why I do not like eating it." So Khalid started eating (it) while Allah's Messenger (ﷺ) was looking at him. An-Nadr said: 'Al-Khazira' (is prepared) from bran while 'Al-Harira' is prepared from milk.

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا هِشَامُ بْنُ يُوسُفَ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي أُمَامَةَ بْنِ سَهْلٍ، عَنِ ابْنِ عَبَّاسٍ، عَنْ خَالِدِ بْنِ الْوَلِيدِ، قَالَ أُتِيَ النَّبِيُّ صلى الله عليه وسلم بِضَبٍّ مَشْوِيٍّ، فَأَهْوَى إِلَيْهِ لِيَأْكُلَ فَقِيلَ لَهُ إِنَّهُ ضَبٌّ، فَأَمْسَكَ يَدَهُ، فَقَالَ خَالِدٌ أَحَرَامٌ هُوَ قَالَ " لاَ، وَلَكِنَّهُ لاَ يَكُونُ بِأَرْضِ قَوْمِي، فَأَجِدُنِي أَعَافُهُ ". فَأَكَلَ خَالِدٌ وَرَسُولُ اللَّهِ صلى الله عليه وسلم يَنْظُرُ. قَالَ مَالِكٌ عَنِ ابْنِ شِهَابٍ بِضَبٍّ مَحْنُوذٍ.
