الزهد لأحمد:١٨٤حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنَا أَبِي حَدَّثَنَا ابْنُ مَهْدِيٍّ عَنْ سُفْيَانَ عَنْ مَنْصُورٍ عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ {فَنَادَى فِي الظُّلُمَاتِ} [الأنبياء 87] قَالَ أَوْحَى اللَّهُ إِلَى الْحُوتِ

أَنْ لَا تَضُرِّي لَهُ عَظْمًا وَلَا لَحْمًا ثُمَّ ابْتَلَعَهُ حُوتٌ آخَرُ {فَنَادَى فِي الظُّلُمَاتِ} [الأنبياء 87] ظُلْمَةُ الْحُوتِ وَحُوتٍ آخَرَ وَظُلْمَةُ الْبَحْرِ
