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.

Narrated Ibn 'Umar (rad): Allah’s Messenger (saw) 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". [Reported by Ahmad and Ibn Majah, and this Hadith has some weakness.]

“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.”

“Two kinds of dead meat have been permitted to us: fish and locusts.”

Allah’s Messenger (saw) said regarding the sea, "It's water is purifying and its dead (animals) are lawful (to eat)." [Al- Arba’a and Ibn Abu Shaiba reported it (this version is of the latter). Ibn Khuzaima and Tirmidhi graded it Sahih. It was also reported by Malik, Shafi'i and Ahmad.]

"Its water is pure (and Purification) and its 'dead meat' is permissible (to eat)."

Abu Huraira said that a man told God’s messenger that he sailed on the sea taking a small quantity of water with him. As he would suffer from thirst if he used this for ablution, he asked whether he might use sea water for that purpose, and received the reply, “Its water is pure, and what dies a natural death in it is lawful food.” Malik, Tirmidhi, Abu Dawud, Nasa'i, Ibn Majah and Darimi transmitted it.

"I was fishing and I had a vessel with me in which I kept water, and I used seawater for ablution. I mentioned that to the Messenger of Allah and he said: 'Its water is a means of purification, and its dead meat is permissible.'"

"A man asked the prophet (PBUH): 'O Messenger of Allah, we travel by sea and we take a little water with us, but if we use it for Wudu', we will go thirsty. Can we perform Wudu' with seawater?' The Messenger of Allah (PBUH) said: 'Its water is a means of purification and its dead meat is permissible.'"

"A man asked the Prophet (PBUH): 'O Messenger of Allah, we travel by sea and we take a little water with us, but if we use it for Wudu', we will go thirsty. Can we perform Wudu', with sea-water?' The Messenger of Allah (PBUH) said: 'Its water is a means of purification and its dead meat is permissible.'"

Yahya related to me from Malik from Safwan ibn Sulaym from Said ibn Salama of the Bani Azraq from al-Mughira ibn Abi Burda of the tribe of Bani Abd ad-Dar that he had heard Abu Hurayra speak about a man who came to the Messenger of Allah, may Allah bless him and grant him peace, and said, "Messenger of Allah! We travel by sea and we do not carry much fresh water with us so if we do wudu with it we go thirsty. Can we do wudu with seawater?" The Messenger of Allah, may Allah bless him and grant him peace, replied, "lts water is pure, and its dead creatures are halal."

“The Messenger of Allah (saw) said: ‘The water of the sea is a means of purification and its dead meat is permissible.’”

A man asked the Messenger of Allah (saws): Messenger of Allah, we travel on the sea and take a small quantity of water with us. If we use this for ablution, we would suffer from thirst. Can we perform ablution with sea water? The Messenger (saws) replied: Its water is pure and what dies in it is lawful food.

He heard Abu Hurairah say: "A man came to the Messenger of Allah and said: "O Messenger of Allah, we travel by sea and carry a small amount of water with us. If we use it for ablution, we will become thirsty. Can we perform ablution with seawater?' The Messenger of Allah said: 'Its water is a means of purification, ad its dead meat is permissible. (i.e. the fish found dead in the sea).'"

The Prophet was asked about seawater, and he said: "Its water is a means of purification, and its dead meat is permissible." (Hasan) Another chain with similar wording.

Yahya related to me from Malik from Abu'z-Zinad from Abu Salama ibn Abd ar-Rahman that some people from al-Jar came to Marwan ibn al- Hakam and asked him about eating what was cast up by the sea. He said, "There is no harm in eating it." Marwan said, "Go to Zayd ibn Thabit and Abu Hurayra and ask them about it, then come to me and tell me what they say." They went to them and asked them, and they both said, "There is no harm in eating it " They returned to Marwan and told him. Marwan said, "I told you."

Malik said that there was no harm in eating fish caught by magians, because the Messenger of Allah, may Allah bless him and grant him peace, said, "In the sea's water is purity, and that which is dead in it is halal. "

Malik said, "If it is eaten when it is dead, there is no harm in who catches it."

"A man asked Allah's Messenger 'O Messenger of Allah! We sail the seas, and we only carry a little water with us. If we use it for Wudu then we will go thirsty. So shall we perform Wudu from the (water of the) sea?' Allah's Messenger said: 'Its water is pure, and its dead are lawful.'"
