Sahih Muslim Book - 43, Hadith - 6168

حَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى ، أَخْبَرَنَا ابْنُ وَهْبٍ ، أَخْبَرَنِي يُونُسُ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عُبَيْدِ اللهِ بْنِ عَبْدِ اللهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ ، عَنْ عَبْدِ اللهِ بْنِ عَبَّاسٍ ، أَنَّهُ تَمَارَى ، هُوَ وَالْحُرُّ بْنُ قَيْسِ بْنِ حِصْنٍ الْفَزَارِيُّ فِي صَاحِبِ مُوسَى عَلَيْهِ السَّلاَمُ ، فَقَالَ ابْنُ عَبَّاسٍ : هُوَ الْخَضِرُ ، فَمَرَّ بِهِمَا أُبَيُّ بْنُ كَعْبٍ الأَنْصَارِيُّ ، فَدَعَاهُ ابْنُ عَبَّاسٍ فَقَالَ : يَا أَبَا الطُّفَيْلِ هَلُمَّ إِلَيْنَا ، فَإِنِّي قَدْ تَمَارَيْتُ أَنَا وَصَاحِبِي هَذَا فِي صَاحِبِ مُوسَى الَّذِي سَأَلَ السَّبِيلَ إِلَى لُقِيِّهِ ، فَهَلْ سَمِعْتَ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَذْكُرُ شَأْنَهُ ؟ فَقَالَ أُبَيٌّ : سَمِعْتُ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ : بَيْنَمَا مُوسَى فِي مَلَإٍ مِنْ بَنِي إِسْرَائِيلَ إِذْ جَاءَهُ رَجُلٌ فَقَالَ لَهُ : هَلْ تَعْلَمُ أَحَدًا أَعْلَمَ مِنْكَ ؟ قَالَ مُوسَى لاَ ، فَأَوْحَى اللَّهُ إِلَى مُوسَى بَلْ عَبْدُنَا الْخَضِرُ قَالَ : فَسَأَلَ مُوسَى السَّبِيلَ إِلَى لُقِيِّهِ ، فَجَعَلَ اللَّهُ لَهُ الْحُوتَ آيَةً ، وَقِيلَ لَهُ : إِذَا افْتَقَدْتَ الْحُوتَ فَارْجِعْ فَإِنَّكَ سَتَلْقَاهُ ، فَسَارَ مُوسَى مَا شَاءَ اللَّهُ أَنْ يَسِيرَ ، ثُمَّ قَالَ لِفَتَاهُ : آتِنَا غَدَاءَنَا ، فَقَالَ فَتَى مُوسَى ، حِينَ سَأَلَهُ الْغَدَاءَ : (أَرَأَيْتَ إِذْ أَوَيْنَا إِلَى الصَّخْرَةِ فَإِنِّي نَسِيتُ الْحُوتَ وَمَا أَنْسَانِيهِ إِلاَّ الشَّيْطَانُ أَنْ أَذْكُرَهُ) ، فَقَالَ مُوسَى لِفَتَاهُ : (ذَلِكَ مَا كُنَّا نَبْغِي فَارْتَدَّا عَلَى آثَارِهِمَا قَصَصًا) فَوَجَدَا خَضِرًا . فَكَانَ مِنْ شَأْنِهِمَا مَا قَصَّ اللَّهُ فِي كِتَابِهِ. إِلاَّ أَنَّ يُونُسَ قَالَ : فَكَانَ يَتَّبِعُ أَثَرَ الْحُوتِ فِي الْبَحْرِ.

It was narrated from 'Abdullah bin 'Abbas that he and Al-Hurr bin Qais bin Hisn Al-Fazari disputed concerning the companion of Musa. Ibn 'Abbas said: "He is Al-Khadr Ubayy bin Ka'b Al-Ansari passed by them and Ibn 'Abbas called him and said: "O Abu At-Tufail, come here. This companion of mine and I are disputing about the companion of Musa whom he wanted to meet. Did you hear the Messenger of Allah (s.a.w) speak about him?" Ubayy said: "I heard the Messenger of Allah (s.a.w) say: "While Musa was among a group of the Children of Israel, a man came to him and said: "Do you know of anyone who is more knowledgeable than you?" Musa' said: "No." Allah revealed to Musa: "No, there is Our slave Al-Khadr." Musa asked how he could meet him, and the fish was made a sign. It was said to him: "When you lose the fish, go back and you will meet him." "Musa traveled as far as Allah willed he should travel, then he said to his servant: "Bring us our morning meal." When Musa asked him for the morning meal, the servant of Musa said: "Do you remember when we betook ourselves to the rock? I indeed forgot the fish; none but Shaitan made me forget to remember it." Musa said to his servant: "That is what we have been seeking." So they went back, retracing their footsteps. Then they found Al-Khadr, and his story is told by Allah in His Book."' But Yunus (a narrator, in his Hadith) said: "He (Musa) followed the traces of the fish in the sea."
