Muwatta Malik, Book 25, Hadith 1063 (In-Book)

Yahya related to me from Malik from Abu'z-Zinad from Abu Salama ibn Abd ar-Rahman from Abu Hurayra and Zayd ibn Thabit that they saw no harm in eating what was cast up by the sea.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ، وَزَيْدِ بْنِ ثَابِتٍ، أَنَّهُمَا كَانَا لاَ يَرَيَانِ بِمَا لَفَظَ الْبَحْرُ بَأْسًا ‏.‏
