That he differed with Hur bin Qais bin Hisn Al-Fazari regarding the companion of (the Prophet) Moses. Ibn ʿAbbas said that he was Al Khadir. Meanwhile, Ubai bin Kaʿb passed by them and Ibn ʿAbbas called him, saying "My friend (Hur) and I have differed regarding Moses' companion, whom Moses asked the way to meet. Have you heard the Prophet ﷺ mentioning something about him? He said, "Yes. I heard Messenger of Allah ﷺ saying, "While Moses was sitting in the company of some Israelites, a man came and asked him. "Do you know anyone who is more learned than you? Moses replied: "No." So Allah sent the Divine Inspiration to Moses: 'Yes, Our slave Khadir (is more learned than you.)' Moses asked (Allah) how to meet him (Khadir). So Allah made the fish as a sign for him and he was told that when the fish was lost, he should return (to the place where he had lost it) and there he would meet him (Al-Khadir). So Moses went on looking for the sign of the fish in the sea. The servant-boy of Moses said to him: Do you remember when we betook ourselves to the rock, I indeed forgot the fish, none but Satan made me forget to remember it. On that Moses said: 'That is what we have been seeking? (18.64) So they went back retracing their footsteps, and found Khadir. (And) what happened further to them is narrated in the Holy Qur'an by Allah. (18.54 up to 18.82)

[Machine] "I have indeed experienced me and my companion in the company of Musa, who asked the way to meet him. Have you heard the Messenger of Allah, ﷺ , mention his story?" He said, "Yes, I heard the Messenger of Allah, ﷺ , say: Among us and Musa, there was a gathering of the Children of Israel, when a man came to him and said, 'Do you know anyone more knowledgeable than you?' He replied, 'No.' So Allah inspired His servant Khidr to ask Musa for the way to meet him. Allah made for him a sign in the form of a fish. It was said to him, 'If you lose the fish, then return, for you will find it.' Ibn Mus'ab said in his narration: So they continued until they reached a place where Musa said to his boy, 'Bring us our lunch, for indeed, we have suffered much fatigue from this journey of ours.' At that moment, they lost the fish. Then they continued, following the traces of the fish in the sea. Musa said, 'They are those whom Allah has mentioned in His Book.'" (Surah Al-Kahf)
