Muwatta Imam Malik 1313

Yahya related to me from Malik from Abdullah ibn Yazid that Zayd ibn Ayyash told him that he had once asked Sad ibn Abi Waqqas about selling white wheat for a type of good barley. Sad asked him which was the better and when he told him the white wheat, he forbade the transaction. Sad said, "I heard the Messenger of Allah, may Allah bless him and grant him peace, being asked about selling dried dates for fresh dates, and the Messenger of Allah, may Allah bless him and grant him peace, said, 'Do the dates diminish in size when they become dry?' When he was told that they did, he forbade that

Yahya related to me from Malik from Da'ud ibn al-Husayn from Abu Sufyan, the mawla of Ibn Abi Ahmad, from Abu Said al-Khudri that the Messenger of Allah, may Allah bless him and grant him peace, forbade muzabana and muhaqala. Muzabana was selling fresh dates for dried dates while they were still on the trees. Muhaqala was renting land in exchange for wheat

Yahya related to me from Malik from Abd al-Hamid ibn Suhayl ibn Abd ar-Rahman ibn Awf from Said ibn al-Musayyab from Abu Said al- Khudri and from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, appointed a man as an agent in Khaybar, and he brought him some excellent dates. The Messenger of Allah, may Allah bless him and grant him peace, said to him, "Are all the dates of Khaybar like this?" He said,"No. By Allah, Messenger of Allah! We take a sa of this kind for two sa or two sa for three." The Messenger of Allah, may Allah bless him and grant him peace, said, "Do not do that. Sell the assorted ones for dirhams and then buy the good ones with the dirhams
