Making a lesson from the story of Prophet Moses studying with a Prophet Khidr as (from Iblis my Teacher / Iblis Guruku by Moeslih Rosyid)

1. Satan makes us forget"And (remember) when Moses said to his disciples," I will not stop (running) before reaching the junction of the two seas, or I will run for years. 'So, when they reached the junction of the two seas that, they forgot their fish. Then the fish jumped into the sea it take its course. And when they had gone further, Moses said to his disciples, 'Bring our food here! Indeed we have been feeling tired, because our journey. 'He replied,' Do you know when to find shelter at the rock, I did indeed forget (told about) the fish, and are not made me forget to tell it, except Satan. And the fish took its way into the sea in a strange way at all. "Musa said," That (the place) we're looking for, "

Then they do not return the original to follow in their footsteps. Then they met a servant of the servants of Us, which We have given him mercy from Us. And we've taught him knowledge from Our presence. Khidr said to Moses, 'May I follow you so that you may teach me the true science among the sciences that have been taught to you?' He replied, 'in fact, that you will not be able to wait with me. And how can you wait for something that you do not have enough knowledge about it? Moses said, "Insha Allah, you will find me as a patient man, and I will not fight you in something else matters. 'He said," If you follow me so do not ask me about anything until I stood up to explain it to you.'
2. Moses was impatientSo they both climbed up when the boat, then Khidr  made a hole. Moses said, 'why are you punching holes in this boat? As a result, your passengers drown. 'Verily ye have done a big mistake. He Khidr, said 'Did not I say,' you never will be patient with me. Moses said, 'Do not punish me to forgot, nor grieve me by raising difficulties in my business.'
 So they up to when they met a boy, then Khidr killed him. Moses said, 'Why did you kill an innocent, not because he killed someone else? Verily, ye have done something unjust. 'Khidr said,' Did I not say unto you that ye will not be impatient with me? 'Moses said,' If I ask thee about anything after (time) this then do not let me be with you. Surely you are old enough to excuse me. '
 And then they walked up to when they came to a resident of a country, they asked were treated to the inhabitants of the land, but the inhabitants of the land did not want to entertain them. Then they get in the country that almost collapsed the walls of the house, then Khidr enforce that wall. Moses said, "If you want, surely you could have taken wages for it.
3. An explanation for the failure of MosesKhidr said, "This is the parting between me and you. Later I will tell you the purpose of your actions can not be impatient about it.
(1) As for the ark is the belief that poor people who work at sea. And, I aimed at damaging the ark, because before them there was a king who seized snatched the ark. (2) And, as for the young man, then keduannya are believers, and we feared that he would encourage both parents to the error. And, we wish that God would they replace them with other children better than his son's holiness and a deeper love (to the mother and father). (3) As for the wall belonged to two orphan boys in the city, and below are property of their savings for both, while his father was a man of deeds. So God wants them to come to maturity, and issue a treasure as a mercy from your Lord. And, is not I do it my own accord. That is the purpose of actions that you can not wait for him. (Quran, al-Kahf [18]: 60-82).
