Yahya related to me from Malik from Sumayy, the mawla of Abu Bakr ibn Abd ar-Rahman that al-Qaqa ibn Hakim and Zayd ibn Aslam sent him to Said ibn al-Musayyab to ask how a woman who was bleeding as if menstruating should do ghusl. Said said, "She does a ghusl to cover from the end of one period to the end of the next, and does wudu for every prayer, and if bleeding overtakes her she should bind her private parts."

Yahya related to me from Malik that he had heard that Sulayman ibn Yasar said, "The fodder of the donkeys of Saad ibn Abi Waqqas ran out and so he told his slave to take some of the family's wheat and buy barley with it, and to only take a like quantity."

Yahya related to me from Malik that he had heard the same as that from al-Qasim ibn Muhammad from Ibn Muayqib ad-Dawsi. Malik said, "This is the way of doing things among us . " Malik said, "The generally agreed on way of doing things among us is that wheat is not sold for wheat, dates for dates, wheat for dates, dates for raisins, wheat for raisins, nor any kind of food sold for food at all, except from hand to hand. If there is any sort of delayed terms in the transaction, it is not good. It is haram. Condiments are not bartered except from hand to hand." Malik said, "Food and condiments are not bartered when they are the same type, two of one kind for one of the other. A mudd of wheat is not sold for two mudds of wheat, nor a mudd of dates for two mudds of dates, nor a mudd of raisins for two mudds of raisins, nor is anything of that sort done with grains and condiments when they are of one kind, even if it is hand to hand. "This is the same position as silver for silver and gold for gold. No increase is halal in the transaction, and only like for like, from hand to hand is halal." Malik said, "If there is a clear difference in foodstuffs which are measured and weighed, there is no harm in taking two of one kind for one of another, hand to hand. There is no harm in taking a sa of dates for two sa of wheat, and a sa of dates for two sa of raisins, and a sa of wheat for two sa of ghee. If the two sorts in the transaction are different, there is no harm in two for one or more than that from hand to hand. If delayed terms enter into the sale, it is not halal ." Malik said, "It is not halal to trade a heap of wheat for a heap of wheat. There is no harm in a heap of wheat for a heap of dates, from hand to hand. That is because there is no harm in buying wheat with dates without precise measurement." Malik said, "With kinds of foods and condiments that differ from each other, and the difference is clear, there is no harm in bartering one kind for another, without precise measurement from hand to hand. If delayed terms enter into the sale, there is no good in it. Bartering such things without precise measurement is like buying it with gold and silver without measuring precisely." Malik said, "That is because you buy wheat with silver without measuring precisely, and dates with gold without measuring precisely, and it is halal. There is no harm in it." Malik said, "It is not good for someone to make a heap of food, knowing its measure and then to sell it as if it had not been measured precisely, concealing its measure from the buyer. If the buyer wants to return that food to the seller, he can, because he concealed its measure and so it is an uncertain transaction. This is done with any kind of food or other goods whose measure and number the seller knows, and which he then sells without measurement and the buyer does not know that. If the buyer wants to return that to the seller, he can return t. The people of knowledge still forbid such a transaction." Malik said, "There is no good in selling one round loaf of bread for two round loaves, nor large for small when some of them are bigger than others. When care is taken that they are like for like, there is no harm in the sale, even if they are not weighed." Malik said, "It is not good to sell a mudd of butter and a mudd of milk for two mudds of butter. This is like what we described of selling dates when two sa of kabis and a sa of poor quality dates were sold for three sa of ajwa dates after the buyer had said to the seller, 'Two sa of kabis dates for three sa of ajwa dates is not good,' and then he did that to make the transaction possible. The owner of the milk puts the milk with his butter so that he can use the superiority of his butter over the butter of the other party to put his milk in with it." Malik said, "Flour for wheat is like for like, and there is no harm in that. That is if he does not mix up anything with the flour and sell it for wheat, like for like. Had he put half a mudd of flour and half of wheat, and then sold that for a mudd of wheat, it would be like what we described, and it would not be good because he would want to use the superiority of his good wheat to put flour along with it. Such a transaction is not good."

Yahya related to me from Malik from Nafi that Sulayman ibn Yasar told him that one time the fodder of the animals of Abd ar-Rahman ibn al-Aswad ibn Abd Yaghuth was finished so he said to his slave, "Take some of your family's wheat as food and buy with it barley, and take only a like quantity.' "

Yahya related to me from Malik that he had heard that Muhammad Sirin used to say, "Do not sell grain on the ears until it is white." Malik said, "If someone buys food for a known price to be delivered at a stated date, and when the date comes, the one who owes the food says, 'I do not have any food, sell me the food which I owe you with delayed terms.' The owner of the food says, 'This is not good, because the Messenger of Allah ﷺ forbade selling food until the deal was completed.' The one who owes the food says to his creditor, 'Sell me any kind of food on delayed terms until I discharge the debt to you.' This is not good because he gives him food and then he returns it to him. The gold which he gave him becomes the price of that which is his right against him and the food which he gave him becomes what clears what is between them. If they do that, it becomes the sale of food before the deal is complete." Malik spoke about a man who was owed food which he had purchased from a man and this man was owed the like of that food by another man. The one who owed the food said to his creditor, "I will refer you to my debtor who owes me the same amount of food as I owe you, so that you may obtain the food which I owe you ." Malik said, "If the man who had to deliver the food, had gone out, and bought the food to pay off his creditor, that is not good. That is selling food before taking possession of it. If the food is an advance which falls due at that particular time, there is no harm in paying off his creditor with it because that is nota sale. It is not halal to sell food before receiving it in full since the Messenger of Allah ﷺ forbade that. However, the people of knowledge agree that there is no harm in partnership, transfer of responsibility and revocation in sales of food and other goods." Malik said, "That is because the people of knowledge consider it as a favour rendered. They do not consider it as a sale. It is like a man lending light dirhams. He is then paid back in dirhams of full weight, and so gets back more than he lent. That is halal for him and permitted. Had a man bought defective dirhams from him as being the full weight, that would not be halal. Had it been stipulated to him that he lend full weight in dirhams, and then he gave faulty ones, that would not be halal for him."

Yahya related to me from Malik that Muhammad ibn Abdullah ibn Abi Maryam asked Said ibn al-Musayyab's advice. "I am a man who buys food with receipts from al-Jar. Perhaps I will buy something for a dinar and half a dirham, and will be given food for a half." Said said, "No. You give a dirham, and take the rest in food." (A half dirham did not exist as a coin.)

Malik said, "Another example of that is that the Messenger of Allah ﷺ forbade the sale called muzabana and granted an indulgence in the ariya for computing the equivalent in dates. It was distinguished between them that the muzabana-sale was based on shrewdness and trade, and the ariya sale was based on a favour rendered, and there was no shrewdness in it." Malik said, "A man must not buy food for a fourth, a third, or a fraction of a dirham on the basis that he be given that food on credit. There is no harm in a man buying food for a fraction of a dirham on credit and then he gives a dirham and takes goods with what remains of his dirham because he gave the fraction he owed as silver, and took goods to make up the rest of his dirham. There is no harm in that transaction." Malik said, "There is no harm in a man placing a dirham with another man and then taking from him known goods for a fourth, third, or a known fraction. If there was not a known price on the goods and the man said, 'I will take them from you for the price of each day,' this is not halal because there is uncertainty. It might be less one time, and more another time, and they would not part with a known sale." Malik said, "If someone sells some food without measuring precisely and does not exclude any of it from the sale and then it occurs to him to buy some of it, it is not good for him to buy any of it except what it would be permitted for him to exclude from it. That is a third or less. If it is more than a third, it becomes muzabana and is disapproved. He must only purchase from what he would be permitted to exclude, and he is only permitted to exclude a third or less than that. This is the way of doing things in which there is no dispute with us."

Yahya related to me from Malik that he had heard that Uthman ibn Affan forbade hoarding .

Yahya related to me from Malik that he had heard that Umar ibn al-Khattab said, "There is no hoarding in our market, and men who have excess gold in their hands should not buy up one of Allah's provisions which he has sent to our courtyard and then hoard it up against us. Someone who brings imported goods through great fatigue to himself in the summer and winter, that person is the guest of Umar. Let him sell what Allah wills and keep what Allah wills."

Yahya related to me from Malik from Yunus ibn Yusuf from Said ibn al-Musayyab that Umar ibn al-Khattab passed by Hatab ibn Abi Baltaa who was underselling some of his raisins in the market. Umar ibn al- Khattab said to him, "Either increase the price or leave our market."

Yahya related to me from Malik from Salih ibn Kaysan from Hasan ibn Muhammad ibn Ali ibn Abi Talib that Ali ibn Abi Talib sold one of his camels called Usayfir for 20 camels to be delivered later.
