Sales Restrictions

"Narrated Abu Bakhtari at-Tai:\n\nI asked Ibn `Abbas about Salam for (the fruits of) date-palms. He replied \"The Prophet (ﷺ) forbade the sale a dates on the trees till they became fit for eating and could be weighed.\" A man asked what to be weighed (as the dates were still on the trees). Another man sitting beside Ibn `Abbas replied, \"Till they are cut and stored.\" Narrated Abu Al-Bakhtari: I heard Ibn `Abbas (saying) that the Prophet (ﷺ) forbade ... etc. as above.\n\nNarrated Abu Al-Bakhtari:\n\nI asked Ibn `Umar about Salam (the fruits of) date-palms. He replied, \"The Prophet (ﷺ) forbade the sale of dates till their benefit becomes evident and fit for eating and also the sale of silver (for gold) on credit.\" I asked Ibn `Abbas about Salam for dates and he replied, \"The Prophet (ﷺ) forbade the sale of dates till they were fit for eating and could be estimated.\"\n\nNarrated Abu Al-Bakhtari:\n\nI asked Ibn `Umar about Salam for dates. Ibn `Umar replied, \"The Prophet (ﷺ) forbade the sale (the fruits) of date-palms until they were fit for eating and also forbade the sale of silver for gold on credit.\" I also asked Ibn `Abbas about it. Ibn `Abbas replied, \"The Prophet (ﷺ) forbade the sale of dates till they were fit for eating, and could be weighed.\" I asked him, \"What is to be weighed (as the dates are on the trees)?\" A man sitting by Ibn `Abbas said, \"It means till they are cut and stored.\"\n\nNarrated `Abdullah:\n\nThe people used to sell camels on the basis of Habal-al-Habala. The Prophet (ﷺ) forbade such sale. Nafi` explained Habal-al-Habala by saying. \"The camel is to be delivered to the buyer after the she-camel gives birth.\""
