aid: Eat, for it is lawful, but it is not my diet.

وَحَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ تَوْبَةَ الْعَنْبَرِيِّ، سَمِعَ الشَّعْبِيَّ، سَمِعَ ابْنَ عُمَرَ، أَنَّ النَّبِيَّ ﷺ كَانَ مَعَهُ نَاسٌ مِنْ أَصْحَابِهِ فِيهِمْ سَعْدٌ وَأُتُوا بِلَحْمِ ضَبٍّ فَنَادَتِ امْرَأَةٌ مِنْ نِسَاءِ النَّبِيِّ ﷺ إِنَّهُ لَحْمُ ضَبٍّ فَقَالَ رَسُولُ اللَّهِ ﷺ " كُلُوا فَإِنَّهُ حَلاَلٌ وَلَكِنَّهُ لَيْسَ مِنْ طَعَامِي " .
