Muwatta Malik #1107

Yahya related to me from Malik from Zayd ibn Aslam that Sad al- Jari, the mawla of Umar ibn al-Khattab asked Abdullah ibn Umar about fish which had killed each other or which had died from severe cold . He said, "There is no harm in eating them.'' Sad said,' 'I then asked Abdullah ibn Amr ibn al As and he said the same."
