Yahya related to me that Malik asked Ibn Shihab about selling animals, two for one with delayed terms. He said, "There is no harm in it." Malik said, "The generally agreed on way of doing things among us is that there is no harm in bartering a camel for a camel like it and adding some dirhams to the exchange, from hand to hand. There is no harm in bartering a camel for a camel like it with some dirhams on top of the exchange, the camels to be exchanged from hand to hand, and the dirhams to be paid within a period." He said, "There is no good however in bartering a camel for a camel like it with some dirhams on top of it, with the dirhams paid in cash and the camel to be delivered later. If both the camel and the dirhams are deferred there is no good in that either." Malik said, "There is no harm in buying a riding camel with two or more pack-camels, if they are from inferior stock. There is no harm in bartering two of them for one with delayed terms, if they are different and their difference is clear. If they resemble each other whether their species are different or not, two are not to be taken for one with delayed terms." Malik said, "The explanation of what is disapproved of in that, is that a camel should not be bought with two camels when there is no distinction between them in speed or hardiness. If this is according to what I have described to you, then one does not buy two of them for one with delayed terms. There is no harm in selling those of them you buy before you complete the deal to somebody other than the one from whom you bought them if you get the price in cash." Malik said, "It is permitted for someone to advance something on animals for a fixed term and describe the amount and pay its price in cash. Whatever the buyer and seller have described is obliged for them. That is still permitted behaviour between people and what the people of knowledge in our land do."
