Narrated Abdullah ibn Abu Awfa ibn Abu Awfa al-Aslami: We made a journey to Syria on an expedition along with the Messenger of Allah صلی اللہ علیہ وسلم . The Nabateans of Syria came to us and we paid in advance to them (in a salam contract) in wheat and olive oil at a specified rate and for a specified time. He asked (by the people): you might have contracted with him who had these things in his possession? He replied: We did not ask them.

Narrated Abdullah ibn Umar: A man paid in advance for a palm-tree. It did not bear fruit that year. They brought their case for decision to the Prophet صلی اللہ علیہ وسلم . He said: for which do you make his property lawful? He then said: Do not pay in advance for a palm-tree till they (the fruits) were clearly in good condition.

Narrated Abu Saeed al-Khudri: The Prophet صلی اللہ علیہ وسلم said: If anyone pays in advance he must not transfer it to someone else before he receives it.

Narrated Abu Saeed Al Khudri: In the time of the Messenger of Allah صلی اللہ علیہ وسلم a man suffered loss affecting fruits he had bought and owed a large debt, so the Messenger of Allah صلی اللہ علیہ وسلم said: Give him sadaqah (alms). So the people gave him sadaqah (alms), but as that was not enough to pay the debt in full, the Messenger of Allah صلی اللہ علیہ وسلم said: Take what you find. But that is all you may have.

Narrated Jabir bin Abdullah: The Messenger of Allah صلی اللہ علیہ وسلم as saying: If you were to sell dried dates to your brother and they were smitten by blight, it will not be allowable for you to take your brother's property unjustly.

Ata said: Blight means anything which obviously damages (the crop), by rain, hail, locust, blast of wind, or fire.

Yahya bin Saeed said: Blight is not effective when less than one-third of goods are damaged. Yayha said: That has been the established practice of Muslims.

Narrated Abu Hurairah: The Messenger of Allah صلی اللہ علیہ وسلم as saying: Excess water should not be withheld so as to prevent (cattle) by it from grass.

Narrated Abu Hurairah: The Messenger of Allah صلی اللہ علیہ وسلم as saying: There are three people who Allah will not address on the Day of Judgement: a man who prevents traveller from the excess water which he has with him; and a man who swears for the goods (for sale) after the afternoon prayer, that is, (he swears) falsely; and a man who takes the oath of allegiance to a ruler (imam); if he gives him (something), he fullfils (the oath of allegiance) to him, if he does not give him (anything), he does not fulfill it.

The tradition mentioned above has also been related by al-'Amash to the same effect through a different chain of narrators. This version adds: "He used: 'Not purify them ; grievously will be their penalty. '" He said about (selling) the goods: I swear by Allah, I was given (the price) so and so for it. The other man considered it to be correct and bought it.
