Do not leave sheep unmilked for a long time, when they are on sale, and whoever buys such an animal has the option of returning it, after milking it, along with a Sa of dates or keeping it. it has been kept unmilked for a long period by the seller (to deceive others).

Allah's Messenger (ﷺ) said, "Do not sell fruits of dates until they become free from all the dangers of being spoilt or blighted; and do not sell fresh dates for dry dates."

Yahya asked, 'How do the Meccans know about it?' I replied, 'They narrated it (from the Prophet (ﷺ) ) through Jabir.' On that, Yahya kept quiet." Sufyan said, "I meant that Jabir belonged to Medina." Sufyan was asked whether in Jabir's narration there was any prohibition of selling fruits before their benefit is evident (i.e. no dangers of being spoilt or blighted). He replied that there was none.

Zaid bin Thabit (ra) said, "In the lifetime of Allah's Messenger (ﷺ), the people used to trade with fruits. When they cut their date-fruits and the purchasers came to recieve their rights, the seller would say, 'My dates have got rotten, they are blighted with disease, they are afflicted with Qusham (a disease which causes the fruit to fall before ripening).' They would go on complaining of defects in their purchases. Allah's Messenger (ﷺ) said, "Do not sell the fruits before their benefit is evident (i.e. free from all the dangers of being spoiled or blighted), by way of advice for they quarrelled too much." Kharija bin Zaid bin Thabit said that Zaid bin Thabit (ra) used not to sell the fruits of his land till Pleiades appeared and one could distinguish the yellow fruits from the red (ripe) ones.

But we barter one Sa of this (type of dates) for two Sas of dates of ours and two Sas of it for three of ours."

Anas said, "The Prophet (ﷺ) forbade the selling of dates till they were almost ripe." We asked Anas, "What does 'almost ripe' mean?" He replied, "They get red and yellow.
