Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) forbade the (people) meeting the caravan (for entering into business transaction with them), and the selling of goods by a townsman on behalf of a man of the desert, and seeking by a woman the divorce of her sister (from her husband), and outbidding (against one another), and tying up the udders (of animals), and buying of (things) in opposition to one's brother.

I saw `Abdullah bin `Umar crossing his legs while sitting in the prayer and I, a mere youngster in those days, did the same. Ibn `Umar forbade me to do so, and said, "The proper way is to keep the right foot propped up and bend the left in the prayer." I said questioningly, "But you are doing so (crossing the legs)." He said, "My feet cannot bear my weight."

Allah's Apostle forbade the selling of things by a town dweller on behalf of a desert dweller; and similarly Najsh was forbidden. And one should not urge somebody to return the goods to the seller so as to sell him his own goods; nor should one demand the hand of a girl who has already been engaged to someone else; and a woman should not try to cause some other woman to be divorced in order to take her place.

I said to Tawus, "I wish you would give up Mukhabara (Sharecropping), for the people say that the Prophet forbade it." On that Tawus replied, "O `Amr! I give the land to sharecroppers and help them. No doubt; the most learned man, namely Ibn `Abbas told me that the Prophet had not forbidden it but said, 'It is more beneficial for one to give his land free to one's brother than to charge him a fixed rental."

Aban bin Sa`id came to the Prophet and greeted him. Abu Huraira said, "O Allah's Apostle! This (Aban) is the murderer of the Ibn Qauqal." (On hearing that), Aban said to Abu Huraira, "How strange your saying is! You, a guinea pig, descending from Qadum Dan, blaming me for (killing) a person whom Allah favored (with martyrdom) with my hand, and whom He forbade to degrade me with his hand.'

We used to participate in the holy wars carried on by the Prophet and we had no women (wives) with us. So we said (to the Prophet ). "Shall we castrate ourselves?" But the Prophet forbade us to do that and thenceforth he allowed us to marry a woman (temporarily) by giving her even a garment, and then he recited: "O you who believe! Do not make unlawful the good things which Allah has made lawful for you."

Some Zanadiqa (atheists) were brought to `Ali and he burnt them. The news of this event, reached Ibn `Abbas who said, "If I had been in his place, I would not have burnt them, as Allah's Apostle forbade it, saying, 'Do not punish anybody with Allah's punishment (fire).' I would have killed them according to the statement of Allah's Apostle, 'Whoever changed his Islamic religion, then kill him.'"

That his father said, "While we were accompanying a funeral procession, Abu Huraira got hold of the hand of Marwan and they sat down before the coffin was put down. Then Abu Sa`id came and took hold of Marwan's hand and said, "Get up. By Allah, no doubt this (i.e. Abu Huraira) knows that the Prophet forbade us to do that." Abu Huraira said, "He (Abu Sa`id) has spoken the truth."

"Allah's Apostle gave the land of Khaibar to the Jews to work on and cultivate and take half of its yield. Ibn `Umar added, "The land used to be rented for a certain portion (of its yield)." Nafi` mentioned the amount of the portion but I forgot it. Rafi` bin Khadij said, "The Prophet forbade renting farms." Narrated 'Ubaidullah Nafi` said: Ibn `Umar said: (The contract of Khaibar continued) till `Umar evacuated the Jews (from Khaibar).
