[Machine] The Prophet Muhammad ﷺ was asked about the water of the sea, to which he replied: "Its water is purifying and its dead creatures are permissible."  

سُئِلَ رَسُولُ اللهِ ﷺ عَنْ مَاءِ الْبَحْرِ فَقَالَ هُوَ الطُّهُورُ مَاؤُهُ الْحِلُّ مَيْتَتُهُ  

[Machine] He said, "We are allowed to consume two dead animals and two bloods: locusts, fish, liver, and spleen." This is a authentic hadith, and it is in the meaning of the mutawatir hadith, and it was narrated by the children of Zaid from their father.  

أَنَّهُ قَالَ أُحِلَّتْ لَنَا مَيْتَتَانِ وَدَمَانِ الْجَرَادُ وَالْحِيتَانِ وَالْكَبِدُ وَالطِّحَالُ هَذَا إِسْنَادٌ صَحِيحٌ وَهُوَ فِي مَعْنَى الْمُسْنَدِ وَقَدْ رَفَعَهُ أَوْلَادُ زَيْدٍ عَنْ أَبِيهِمْ  

[Machine] The Messenger of Allah ﷺ said that two things are permissible for us: dead meat and blood. As for the dead meat, it refers to locusts and fish, while the blood refers to spleen and liver. All of these are from the weak animals, which Yahya bin Ma'een had declared as such. However, Ahmad bin Hanbal and Ali bin Al-Madini considered Abdullah bin Zaid as reliable, except that the authentic narration from this hadith is the first one.  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ أُحِلَّتْ لَنَا مَيْتَتَانِ وَدَمَانِ فَأَمَّا الْمَيْتَتَانِ فَالْجَرَادُ وَالْحُوتُ وَأَمَّا الدَّمَانِ فَالطِّحَالُ وَالْكَبِدُ أَوْلَادُ زَيْدٍ هَؤُلَاءِ كُلُّهُمْ ضُعَفَاءُ جَرَّحَهُمْ يَحْيَى بْنُ مَعِينٍ وَكَانَ أَحْمَدُ بْنُ حَنْبَلٍ وَعَلِيُّ بْنُ الْمَدِينِيِّ يُوَثِّقَانِ عَبْدَ اللهِ بْنَ زَيْدٍ إِلَّا أَنَّ الصَّحِيحَ مِنْ هَذَا الْحَدِيثِ هُوَ الْأَوَّلُ
