Hazrat Saeed bin Jubair says that I said to Hazrat Ibn Abbas (may Allah be pleased with them) that Nauf Bikali thinks that the Musa (of Hazrat Khidr, peace be upon him) is not the Musa of Bani Israel, but rather some other Musa. Ibn Abbas (may Allah be pleased with them) said, "The enemy of Allah lies! Hazrat Ubayy bin Ka'b (may Allah be pleased with him) narrated this hadith to me, that the Holy Prophet (peace and blessings be upon him) said: Once Hazrat Musa (peace be upon him) was standing and giving a sermon before Bani Israel. After the sermon ended, a man asked, 'Who is the most knowledgeable person?' Hazrat Musa (peace be upon him) replied, 'I am the most knowledgeable.' Allah Almighty revealed to Hazrat Musa (peace be upon him) that among My servants, there is a servant who is more knowledgeable than you. Hazrat Musa (peace be upon him) said, 'O Lord, how can I meet him?' It was commanded, 'Take a (roasted) fish with you in a basket (and set out on your journey). Where that fish is lost, you will find that person.' Hazrat Musa (peace be upon him) took a fish, put it in the basket, and set out, taking with him a servant, Yusha bin Nun. As they walked, when they reached a rock, both (stopped and) Hazrat Musa (peace be upon him) lay his head on the rock and slept. Meanwhile, the fish fluttered out of the basket and made its way into the river, making a tunnel as it went. Hazrat Musa (peace be upon him) woke up, and Musa said to his servant, 'We have become very tired from this journey, now bring the food.' And Musa had not felt any fatigue until they had passed the appointed place; rather, he began to feel tired only after passing the appointed place. The servant said, 'What can I say? When we reached that rock, I forgot the fish there (and I did not mention it to you).' Hazrat Musa (peace be upon him) said, 'That is the place we were seeking.' So, retracing their steps, they returned, step by step. As soon as they reached the rock, they saw a man with his head wrapped in a cloth. Hazrat Musa (peace be upon him) greeted him with salam. Khidr said, 'Where is salam customary in your land? (How did you greet me with salam?)' Hazrat Musa (peace be upon him) said, 'I am Musa.' Khidr said, 'The Musa of Bani Israel?' I said, 'Yes.' After that, Hazrat Musa (peace be upon him) said, 'May I accompany you on the condition that you teach me some of the knowledge which Allah has granted you?' Hazrat Khidr (peace be upon him) said, 'You will not be able to remain patient with me (you will interrupt in between), because Allah Almighty has given me a special portion which He has not given you, and He has given you knowledge of which I am unaware.' (Hazrat Musa (peace be upon him) said, 'If Allah wills, you will find me steadfast, I will not disobey your command.') Eventually, both set out walking along the riverbank, and there was no boat. Meanwhile, a boat passed by; they spoke to the boatmen about boarding. The people recognized Hazrat Khidr (peace be upon him), so the boatmen let both of them board without fare. After that, Khidr (peace be upon him) inspected the boat, took out an adze, and removed a plank from the boat. Hazrat Musa (peace be upon him) said, 'What have you done? These people let us board without fare, and you have damaged their boat and wanted to drown everyone! You have done a strange thing.' Khidr (peace be upon him) said, 'Did I not tell you that you would not be able to remain patient with me?' Hazrat Musa (peace be upon him) said, 'Do not call me to account for my forgetfulness, and do not make my task difficult for me.' Meanwhile, a bird came and dipped its beak into the sea. Hazrat Khidr (peace be upon him) said, 'My knowledge and your knowledge cannot diminish Allah's knowledge even as much as this bird has diminished the water of the sea.' Then both of them disembarked from the boat and set out. On the seashore, a boy was playing with other children. Khidr (peace be upon him) caught him by the head and broke his neck with his hand. Hazrat Musa (peace be upon him) said, 'You have killed an innocent soul without reason; you have done a terrible thing.' Khidr (peace be upon him) said, 'Did I not tell you that you would not be able to remain patient with me?' Musa said, 'Alright, after this, if I ask you anything, then do not keep me with you; you have already excused me much.' Eventually, both set out again. As they walked, they reached a village and asked the villagers for food, but they refused to host them. There they saw a wall that was about to collapse; Hazrat Khidr (peace be upon him) gestured with his hand and set it straight.
