That he differed with Al-Hurr bin Qais bin Hisn Al-Fazari about the companion of Moses, (i.e., whether he was Kha,dir or not). Ubai bin Ka`b Al-Ansari passed by them and Ibn `Abbas called him saying, 'My friend (Hur) and I have differed about Moses' Companion whom Moses asked the way to meet. Did you hear Allah's Apostle mentioning anything about him?" Ubai said, "Yes, I heard Allah's Apostle saying, "While Moses was sitting in the company of some Israelites a man came to him and asked, 'Do you know Someone who is more learned than you (Moses)?' Moses said, '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 it was said to him, 'When you lose the fish, go back (to the place where you lose it) and you will meet him.' So Moses went on looking for the sign of the fish in the sea. The boy servant of Moses (who was accompanying him) said to him, 'Do you remember (what happened) when we betook ourselves to the rock? I did indeed forget to tell you (about) the fish. None but Satan made me forget to tell you about it' (18.63) Moses said: 'That is what we have been seeking." Sa they went back retracing their footsteps. (18.64). So they both found Kadir (there) and then happened what Allah mentioned about them (in the Qur'an)!' (See 18.60- 82)

86 Malik related to me from Musa ibn Maysara that he heard a man ask Said ibn al-Musayyab, "I am a man who sells for a debt." Said said, "Do not sell except for what you take to your camel."

Malik spoke about a person who bought goods from a man provided that he provide him with those goods by a specific date, either in time for a market in which he hoped for their saleability, or to fulfil a need at the time he stipulated. Then the seller failed him about the date, and the buyer wanted to return those goods to the seller. Malik said, "The buyer cannot do that, and the sale is binding on him. If the seller does bring the goods before the completion of the term, the buyer cannot be forced to take them."

Malik spoke about a person who bought food and measured it. Then some one came to him to buy it and he told him that he had measured it for himself and taken it in full. The new buyer wanted to trust him and accept his measure. Malik said, "Whatever is sold in this way for cash has no harm in it but whatever is sold in this way on delayed terms is disapproved of until the new buyer measures it out for himself. The sale with delayed terms is disapproved of because it leads to usury and it is feared that it will be circulated in this way without weight or measure. If the terms are delayed it is disapproved of and there is no disagreement about that with us."

Malik said, "One should not buy a debt owed by a man whether present or absent, without the confirmation of the one who owes the debt, nor should one buy a debt owed to a man by a dead person even if one knows what the deceased man has left. That is because to buy that is an uncertain transaction and one does not know whether the transaction will be completed or not completed."

He said, "The explanation of what is disapproved of in buying a debt owed by someone absent or dead, is that it is not known what unknown debtor may be connected to the dead person. If the dead person is liable for another debt, the price which the buyer gave on strength of the debt may become worthless."

Malik said, "There is another fault in that as well. He is buying something which is not guaranteed for him, and so if the deal is not completed, what he paid becomes worthless. This is an uncertain transaction and it is not good."

Malik said, "One distinguishes between a man who is only selling what he actually has and a man who is being paid in advance for something which is not yet in his possession. The man advancing the money brings his gold which he intends to buy with. The seller says, 'This is 10 dinars. What do you want me to buy for you with it?' It is as if he sold 10 dinars cash for 15 dinars to be paid later. Because of this, it is disapproved of. It is something leading to usury and fraud."

I said to Ibn `Abbas, "Nauf Al-Bikali claims that Moses, the companion of Al-Khadir was not the Moses of the children of Israel" Ibn `Abbas said, "The enemy of Allah (Nauf) told a lie." Narrated Ubai bin Ka`b that he heard Allah's Apostle saying, "Moses got up to deliver a speech before the children of Israel and he was asked, Who is the most learned person among the people?' Moses replied, 'I (am the most learned).' Allah admonished him for he did not ascribe knowledge to Allah alone. So Allah revealed to him: 'At the junction of the two seas there is a slave of Ours who is more learned than you.' Moses asked, 'O my Lord, how can I meet him?' Allah said, 'Take a fish and put it in a basket (and set out), and where you, will lose the fish, you will find him.' So Moses (took a fish and put it in a basket and) set out, along with his boy-servant Yusha` bin Noon, till they reached a rock (on which) they both lay their heads and slept. The fish moved vigorously in the basket and got out of it and fell into the sea and there it took its way through the sea (straight) as in a tunnel). (18.61) Allah stopped the current of water on both sides of the way created by the fish, and so that way was like a tunnel. When Moses got up, his companion forgot to tell him about the fish, and so they carried on their journey during the rest of the day and the whole night. The next morning Moses asked his boy-servant 'Bring us our early meal; no doubt, we have suffered much fatigue in this journey of ours.' (18.62) Moses did not get tired till he had passed the place which Allah had ordered him to seek after. His boy-servant then said to him,' 'Do you remember when we be-took ourselves to the rock I indeed forgot the fish, none but Satan made me forget to remember it. It took its course into the sea in a marvelous way.' (18.63) There was a tunnel for the fish and for Moses and his boy-servant there was astonishment. Moses said, 'That is what we have been seeking'. So they went back retracing their footsteps. (18.64) They both returned, retracing their steps till they reached the rock. Behold ! There they found a man covered with a garment. Moses greeted him. Al-Khadir said astonishingly. 'Is there such a greeting in your land?' Moses said, 'I am Moses.' He said, 'Are you the Moses of the children of Israel?' Moses said, 'I have come to you so that you may teach me of what you have been taught. Al-Khadir said, 'You will not be able to have patience with me. (18.66) O Moses! I have some of Allah's knowledge which He has bestowed upon me but you do not know it; and you too, have some of Allah's knowledge which He has bestowed upon you, but I do not know it." Moses said, "Allah willing, you will find me patient, and I will not disobey you in anything.' (18.6) Al-Khadir said to him. 'If you then follow me, do not ask me about anything until I myself speak to you concerning it.' (18.70), After that both of them proceeded along the sea coast, till a boat passed by and they requested the crew to let them go on board. The crew recognized Al-Khadir and allowed them to get on board free of charge. When they got on board suddenly Moses saw that Al-Khadir had pulled out one of the planks of the boat with an adze. Moses said to him.' These people gave us a free lift, yet you have scuttled their boat so as to drown its people! Truly, you have done a dreadful thing.' (18.71) Al-Khadir said, 'Didn't I say that you can have no patience with me ?' (18.72) Moses said, 'Call me not to account for what I forgot and be not hard upon me for my affair (with you.)" (18.73) Allah's Apostle said, "The first excuse given by Moses, was that he had forgotten. Then a sparrow came and sat over the edge of the boat and dipped its beak once in the sea. Al-Khadir said to Moses, 'My knowledge and your knowledge, compared to Allah's knowledge is like what this sparrow has taken out of the sea.' Then they both got out of the boat, and while they were walking on the sea shore, Al-Khadir saw a boy playing with other boys. Al-Khadir got hold of the head of that boy and pulled it out with his hands and killed him. Moses said, 'Have you killed an innocent soul who has killed nobody! Truly, you have done an illegal thing.' (18.74) He said, "Didn't I tell you that you can have no patience with me?' (18.75) (The sub narrator said, the second blame was stronger than the first one.) Moses said, 'If I ask you about anything after this, keep me not in your company, you have received an excuse from me.' (18.76) Then they both proceeded until they came to the inhabitants of a town. They asked them food but they refused to entertain them. (In that town) they found there a wall on the point of falling down. (18.77) Al-Khadir set it up straight with his own hands. Moses said, 'These are people to whom we came, but they neither fed us nor received us as guests. If you had wished, you could surely have exacted some recompense for it. Al-Khadir said, 'This is the parting between me and you ..that is the interpretation of (those things) over which you were unable to hold patience.' (18.78-82) Allah's Apostle said, "We wished that Moses could have been more patient so that Allah might have described to us more about their story."
