Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) forbade the sale of Mulamasah and Munabadhah.

Sayyiduna Abu Hurairah (may Allah be pleased with him) said that the Noble Prophet (peace and blessings be upon him) forbade two fasts and two types of transactions: fasting on Eid al-Fitr and Eid al-Adha, and buying and selling through Mulamasah and Munabadah.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) forbade two types of clothing and two types of transactions. In transactions, he forbade mulamasah and munabadhah. The form of mulamasah was that a person (the buyer) would merely touch the garment of another (the seller) at any time, day or night (and the sale would be concluded just by touching, without seeing it). Only touching was sufficient; it was not opened and inspected. The form of munabadhah was that a person would throw his garment towards another, and the other would throw his garment, and without seeing and without mutual consent, the sale would be concluded just by this act. And regarding the two garments (which the Prophet, peace and blessings be upon him, forbade to wear): one is ishtimal as-samma'. The form of samma' was that a person would drape his garment (a sheet) over one shoulder in such a way that one side (the private parts) would become exposed, and there would be no other garment covering it. The method of the second garment was that, while sitting, a person would tie his waist and thighs with one garment, and there would be no garment over the private parts.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them) narrated that the Messenger of Allah (peace and blessings be upon him) forbade the sale of the unborn offspring of a pregnant animal. This type of sale was prevalent in the days of ignorance. A person would buy a camel or a she-camel and set the payment term as follows: when a she-camel gives birth, and then the offspring in her womb grows up and gives birth.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them) narrated that the Messenger of Allah (peace and blessings be upon him) said: No person should interfere in the buying and selling of his brother.

Sayyiduna Abu Huraira (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: Do not go out to meet (trade) caravans (with the intention of buying their goods before they reach the city). No one should sell over the sale of his brother, and no one should practice najsh (artificially inflating prices), and no townsman should sell for a villager, and do not tie up the udders of goats (to deceive buyers by making them appear full of milk). But if someone buys an animal in this (last) situation, then after milking it, he has two options: if he is satisfied with the sale, he may keep the animal, and if he is not satisfied, he may return it along with a sa’ (measure) of dates.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Noble Messenger (peace and blessings of Allah be upon him) forbade intercepting (trading) caravans, and that a townsman should not sell goods on behalf of a villager, and that a woman should not stipulate the divorce of her (religious or blood-related) sister, and that one should not bid against his brother’s bid. Likewise, he forbade najsh (artificially inflating prices) and tasriyah (concealing defects in goods).

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said that whoever buys a lactating goat and wants to return it, he should give along with it one sa’ (measure), and the Noble Prophet (peace and blessings of Allah be upon him) forbade buying from caravan people (who bring goods to sell) by going ahead to meet them.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated that the Prophet (peace and blessings of Allah be upon him) said: "Do not go out to meet (trade) caravans (before they reach the market), and no townsman should sell goods on behalf of a villager." (The narrator says:) I asked Sayyiduna Ibn Abbas about the meaning of the Prophet’s statement that no townsman should sell the goods of a villager. He replied: "It means that he should not act as a broker."

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrated that we were forbidden from a townsman selling the merchandise of a villager.
