The Prophet ﷺ said concerning the water of the sea, "Its water is pure, and its dead creatures are lawful to eat."
حدثنا عبد الرحمن عن مالك عن صفوان بن سليم عن سعيد بن سلمة من آل ابن الأزرق عن المغيرة بن أبي بردة
عن النبي ﷺ قال في ماء البحر هو الطهور ماؤه الحلال ميتته
Its chain of transmission is sahih. Safwan bin Salim, with the sin pronounced with a damma, his reliability was already established at 1992, and we add here that Bukhari included his biography in Kabir 2/308-309, and mentioned that Sufyan bin Uyayna said, "Whenever I saw him, I knew that he feared Allah." Ibn Abu Hatim also included him in Jarh wa Tadil 1/423-424, and he reported from Abdullah bin Ahmad, from his father, who said, "Safwan bin Salim is trustworthy, one of the best of Allah's righteous servants." It will come at 9088 that he was the freedman of Humayd bin Abdul-Rahman bin Awf.Saeed bin Salama, of the family of Banu Azraq, is trustworthy. Nasai and others confirmed his reliability. Bukhari included his biography in Kabir 1/437-438, and Ibn Abu Hatim in Jarh wa Tadil 1/29 without mentioning any criticism of him. The great scholars graded his hadith here as sahih, as will be shown. It has been established in the original manuscripts of the Musnad at this point that his lineage was given as "Zurayqi," as if he were attributed to Banu Zurayq with the za pronounced with a damma. This is certainly an error, for everyone who wrote his biography and mentioned his lineage said he was "of Banu Azraq," as in the Muwatta, or "of the family of Banu Azraq," and these were of Banu Makhzum among Quraysh. As for Banu Zurayq, to whom the attribution "Zurayqi" belongs, they are from a clan of the Ansar from Khazraj.Mughira bin Abu Burda al-Kinani, who was of Banu Abdul-Dar bin Qusay, was a trustworthy Follower. Nasai, Ibn Hibban, and others confirmed his reliability. Ibn Saad mentioned him in Tabaqat 5/178 without giving a full biography of him. Bukhari included his biography in Kabir 3/4/323-324, and mentioned that he heard from Abu Hurairah. Abul-Arab Tamimi included his biography in Tabaqat Ulama Ifriqiyya, pages 22-23, and said, "He was a native of Ifriqiyya, and was one of the notable figures among its people. He fought in the campaign against Constantinople, and commanded the army of Ifriqiyya that took part in that campaign." He also referred to this hadith of his as found in the Muwatta. Abu Bakr Maliki included his biography in Riyad Nufus, pages 80-81, in a fine biographical entry, and said, "He was a man of merit, counted among the Followers." He mentioned that he campaigned with Ibn Nusayr in Maghrib and Andalus, and referred to this hadith of his as transmitted from Malik. He said, "When Yazid bin Abu Muslim, governor of Ifriqiyya, was killed, the people of Ifriqiyya, those of religion and merit, gathered and agreed to appoint Mughira as governor, knowing his religious commitment and resolve. But he refused, preferring safety for himself, and he and his son agreed to flee from that responsibility." The hadith appears in the Muwatta, page 22, in its longer form.The longer version of this narration will come at 8720, from Abu Salama, who is Mansur bin Salama Khuzai, from Malik. We will mention its sourcing based on the longer version. Shafii related it in Umm 1/2, from Malik. Bukhari related it in Kabir 1/2/437-438, by way of Malik, with his characteristically precise and concise indication, then he pointed to another route for it. Darimi related it at 1/186. Abu Dawud at 1/83, 1/31-32 in Aun Mabud, Tirmidhi at 1/72-74, and Nasai at 1/21. Ibn Majah at 1/79, Ibn Jarud at pages 30-31, and Hakim at 1/140-141, all of them by way of Malik. Then Hakim mentioned many other routes for it at 1/141-143. Tirmidhi said, "This hadith is hasan sahih." Hafiz said in Tahzib 4/42, in the biography of Saeed bin Salama, its narrator from Mughira, "Bukhari graded his hadith sahih, as related from him by Tirmidhi in Ilal Mufrad." He also said, at 10/257, in the biography of Mughira bin Abu Burda, "His hadith from Abu Hurairah was graded sahih, in Bahr, by Ibn Munzir, Khattabi, Tahawi, Ibn Manda, Hakim, Ibn Hazm, Bayhaqi, Abdul-Haqq, and others." This concise narration will also come, with a reference to it, from Abdul-Rahman bin Mahdi as well, at 9089. The hadith will also come in its longer form, from two other routes, at 8899 and 9088.
