وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«أُحِلَّتْ لَنَا مَيْتَتَانِ وَدَمَانِ، فَأَمَّا الْمَيْتَتَانِ: فَالْجَرَادُ وَالْحُوتُ، وَأَمَّا الدَّمَانُ: فَالطِّحَالُ وَالْكَبِدُ»
Narrated Ibn Umar (rad): The Messenger of Allah (sallallahu alayhi wa sallam) said: “Two types of dead animals and two types of bloods have been made lawful for us, the two types of dead animals are locusts and fish (seafood), while the two types of bloods are the liver and the spleen”.
