Ibn 'Umar reported that a person asked Allah's Messenger (ﷺ) as he was sitting on the pulpit about the eating of the lizard, whereupon he said:I neither eat it, nor do I prohibit it.
وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ سَأَلَ رَجُلٌ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهُوَ عَلَى الْمِنْبَرِ عَنْ أَكْلِ الضَّبِّ فَقَالَ " لاَ آكُلُهُ وَلاَ أُحَرِّمُهُ " .
