"I said to Ibn 'Abbas: 'Nawf Al-Bikali claims that Musa, of Banu Isra'il is not the companion of Al-Khidr. He said: 'The enemy of Allah has lied. I heard Ubayy bin Ka'b saying: "I heard the Messenger of Allah (SAW) say 'Musa stood to deliver a Khutbah to the children of Isra'il. He was asked: "Who is the most knowledgeable among the people?" He said: "I am the most knowledgeable." So Allah admonished him, since he did not refer the knowledge back to Him. Allah revealed to him: "A slave, among My slaves at the junction of the two seas, is more knowledgeable than you." So Musa said: "O Lord! How can I meet him?"

Sufyan (one of the narrators) said: "People claim that there is a spring of life at that rock, no dying person has its water poured over him, but he becomes alive, and the fish came in contact with some of it, so when the water dropped on it he became alive." "He [the Prophet (SAW)] said: 'They retraced their tracks until they arrived at the rock to see a man covered in a garment. Musa greeted him, and he replied: Is there such a greeting in your land?
