Muwatta Malik, Book 25, Hadith 10 (USC-MSA) ⓘ

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."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ سَعْدٍ الْجَارِيِّ، مَوْلَى عُمَرَ بْنِ الْخَطَّابِ أَنَّهُ قَالَ سَأَلْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ عَنِ الْحِيتَانِ، يَقْتُلُ بَعْضُهَا بَعْضًا أَوْ تَمُوتُ صَرَدًا فَقَالَ لَيْسَ بِهَا بَأْسٌ ‏.‏ قَالَ سَعْدٌ ثُمَّ سَأَلْتُ عَبْدَ اللَّهِ بْنَ عَمْرِو بْنِ الْعَاصِ فَقَالَ مِثْلَ ذَلِكَ ‏.‏
