Narrated by Abu Bakhtari At-Tai
I asked Ibn ‘Abbas (radiallaahu `anhu) about Salam for (the fruits of) date-palms. He replied “The Prophet (sallallaahu `alayhi wasallam) 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 (radiallaahu `anhu) replied, “Till they are cut and stored.” Narrated Abu Al-Bakhtari: I heard Ibn Abbas (radiallaahu `anhu) (saying) that the Prophet (sallallaahu `alayhi wasallam) forbade … etc. as above.

I asked Ibn Umar (radiallaahu `anhu) about Salam (the fruits of) date-palms. He replied, “The Prophet (sallallaahu `alayhi wasallam) 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 (radiallaahu `anhu) about Salam for dates and he replied, “The Prophet (sallallaahu `alayhi wasallam) forbade the sale of dates till they were fit for eating and could be estimated.”

Volume 3, Book 35, Number 452 :
Narrated by Abu Al-Bakhtari
I asked Ibn ‘Umar (radiallaahu `anhu) about Salam for dates. Ibn ‘Umar (radiallaahu `anhu) replied, “The Prophet (sallallaahu `alayhi wasallam) forbade the sale (the fruits) of datepalms until they were fit for eating and also forbade the sale of silver for gold on credit.” I also asked Ibn ‘Abbas (radiallaahu `anhu) about it. Ibn ‘Abbas (radiallaahu `anhu) replied, “The Prophet (sallallaahu `alayhi wasallam) 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 (radiallaahu `anhu) said, “It means till they are cut and stored.”

As described in the above ahadith, one should not make any advance payments for fruits that are still on trees and cannot be weighed/measured.
