It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) forbade the sale of water, taking a fee for the mating of a camel, and a man selling his land (together with) its water rights. All of these chains are sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record them.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) forbade the sale of water. Al-Husayn bin Waqid is alone in narrating this, and it is gharib (singular) and sahih (authentic).

It is narrated from Sayyiduna Abdullah bin Abi Awfa al-Aslami (may Allah be pleased with him): We went on a military expedition with the Messenger of Allah (peace and blessings be upon him) in Syria, and some farmers (Anbat, Nabataeans) of Syria used to come to us. We would make salam (advance-payment) contracts with them for wheat and olive oil at a fixed price and for a fixed term. He was asked: Did they have those goods (at the time)? He replied: We did not ask them about that. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever accepts a Muslim's request to cancel (a sale), Allah Almighty will forgive his stumbles (on the Day of Resurrection)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever makes two sales in one sale, it is permissible for him to take the lower price of the two (the original price); otherwise it is usury (riba)." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Muhammad bin al-Ash'ath (may Allah have mercy on him) that Sayyiduna al-Ash'ath bin Qays (may Allah be pleased with him) bought some slaves from among the slaves of the khumus (the one-fifth share) from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) for twenty thousand. Then Sayyiduna Abdullah (may Allah be pleased with him) sent to him demanding their price, and al-Ash'ath (may Allah be pleased with him) said: I took them for only ten thousand. Abdullah (may Allah be pleased with him) said: Then choose a man who will judge between me and you. Al-Ash'ath (may Allah be pleased with him) said: You yourself are (the judge) between me and yourself. So Abdullah (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "When the seller and the buyer disagree and neither has any evidence, then what the owner of the goods says is to be accepted, or else the two of them cancel the sale." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

She said that the Messenger of Allah (peace and blessings be upon him) said: "The purest of what a man eats is from his own earnings, and his children too are part of his own earnings."
