Sunan Ibn Majah, Hadith 3314 ⓘ
It was narrated from ‘Abdullah bin ‘Umar that the Messenger of Allah said: “Two kinds of dead meat and two kinds of blood have been permitted to us. The two kinds of dead meat are fish and locusts, and the two kinds of blood are the liver and spleen.”
حَدَّثَنَا أَبُو مُصْعَبٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " أُحِلَّتْ لَنَا مَيْتَتَانِ وَدَمَانِ فَأَمَّا الْمَيْتَتَانِ فَالْحُوتُ وَالْجَرَادُ وَأَمَّا الدَّمَانِ فَالْكَبِدُ وَالطِّحَالُ " .
