وَعَنِ ابْنِ عُمَرَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: ” أُحِلَّتْ لَنَا مَيْتَتَانِ وَدَمَانِ: الْمَيْتَتَانِ: الْحُوتُ وَالْجَرَادُ وَالدَّمَانِ: الْكَبِدُ وَالطِّحَالُ ” . رَوَاهُ أحمدُ وابنُ مَاجَه وَالدَّارَقُطْنِيّ

Ibn ‘Umar reported God’s messenger as saying, “Two types of animals which have died a natural death and two types of blood have been made allowable to us, the two which die a natural death being the fish and the locust, and the two types of blood being the liver and the spleen.” Ahmad, Ibn Majah and Daraqutni transmitted it.
