أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهُوَ عَلَى الْمِنْبَرِ سُئِلَ عَنِ الضَّبِّ فَقَالَ ‏"‏ لاَ آكُلُهُ وَلاَ أُحَرِّمُهُ ‏"‏ ‏.‏

It was narrated from Ibn 'Umar that

the Messenger of Allah was asked about mastigures when he was on the Minbar and he said? "I do not eat them, but I do not say that they are Haram."
