Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates a similar narration about the Noble Prophet (peace and blessings of Allah be upon him), however, in it are these words: The Noble Prophet (peace and blessings of Allah be upon him) said: "The rebellious camel is returned."

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: I used to trade camels in Baqi‘. Sometimes I would sell them for dinars and receive dirhams instead, and sometimes I would sell them for dirhams and receive dinars instead. This one would take in place of that, and that one would be given in place of this. Once I presented myself before the Prophet (peace and blessings of Allah be upon him), and he was at that time in the house of Lady Hafsa. I said:“O Messenger of Allah! I want to ask you a question. I trade camels in Baqi‘, and sometimes I sell them for dinars but receive dirhams, and sometimes I sell them for dirhams and receive dinars. I take this in place of that, and that in place of this.”The Prophet (peace and blessings of Allah be upon him) said:“There is no harm in this, as long as you take according to the rate of that day, as long as you both do not separate or no condition is set between you.”In another narration, there is some variation in the wording.

Sayyiduna Ubadah bin Samit (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said:“Gold for gold, silver for silver, dates for dates, wheat for wheat, barley for barley, and salt for salt can only be sold in equal amounts, hand to hand. But when these types differ, then sell as you wish, as long as it is hand to hand (i.e., not on credit).”

Mu’ammar bin ‘Abdullah narrates that he sent his slave with one sa’ of wheat and said:“Sell this one sa’ and bring back whatever you buy with it.”The slave went and received one sa’ and a little more in exchange. When he returned and informed him about it, Mu’ammar said:“Why did you do that? Go and return it, and only make an equal exchange, for I heard the Prophet (peace and blessings be upon him) say: ‘Grain for grain.’”He meant that only equal amounts can be given and taken. In those days, this was our food. The slave said:“But these are not the same.”Mu’ammar replied:“I fear that they are equivalent.”

It is narrated about Mu’ammar bin ‘Abdullah that he sent his slave with a sa’ of wheat and said:“Sell it for a sa’ and bring back whatever you buy with it.”The slave went and received a sa’ and a little more than a sa’. When he returned and informed him about it, Mu’ammar said:“Why did you interfere in this? Go and return it, and only make an equal exchange, because I heard the Prophet (peace and blessings of Allah be upon him) say: Grain for grain can only be exchanged equally.”The narrator says: In those days, our food used to be barley. It was said to Mu’ammar: This is not like it. So he replied:“I think it is like it.”

Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "The one who takes usury and the one who gives it are equal (in sin)."

Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings of Allah be upon him) said: "Dinar should be exchanged for dinar, dirham for dirham, without any additional payment. Whoever needs silver should trade it for gold, and whoever needs gold should trade it for silver, but this transaction must be hand to hand."

Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet Muhammad (peace be upon him) said during the Farewell Pilgrimage: "Behold, a Muslim is the brother of another Muslim; it is not lawful for him to take his brother's blood or anything from his wealth, except what he gives willingly. Beware! Have I conveyed (the message)?" The people said, "Yes." The Prophet said, "O Allah! Bear witness."

Sayyiduna Anas (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "No person should accompany his brother until he gives him permission of his own accord."

Sayyiduna Amr bin Yathrabi رضي الله عنه narrates that I was present with the Prophet Muhammad صلى الله عليه وسلم at Mina during the Farewell Pilgrimage. I heard him say: "It is not permissible for any person to take anything from his brother's wealth except that which he (the other person) gives willingly." The narrator says: At that time I asked: "O Messenger of Allah! What is your opinion about this: if I find my cousin's goats in front of me and I take one of the goats and slaughter it, will there be any sin upon me regarding this?" The Prophet Muhammad صلى الله عليه وسلم said: "If you are faced with a goat and at that time you have a knife in your hand and something to tie its legs, even then do not touch that goat."
