عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أُحِلَّتْ لَنَا مَيْتَتَانِ وَدَمَانِ فَأَمَّا الْمَيْتَتَانِ فَالْحُوتُ وَالْجَرَادُ فَأَمَّا الدَّمَانِ فَالْكَبِدُ وَالطِّحَالُ
Sayyiduna Abdullah bin Amr (may Allah be pleased with them) narrates that the Noble Prophet (peace and blessings be upon him) said: Two dead animals and two types of blood have been made lawful for us; the two dead animals are fish and locusts, and the two types of blood are liver and spleen.
