Paying in advance (salam) for food and dates

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: When the Prophet (peace and blessings be upon him) came to Madinah, the people used to make salam transactions in dates for one, two, and three years. The Prophet (peace and blessings be upon him) said: "Whoever makes a salam sale in dates should do so with a known measure and weight, and for an appointed time."

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: When the quantity and the time are specified in a salam transaction, there is no harm in it.

Likewise is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both).

Something similar is reported from Abu Ishaq from al-Aswad.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that when the quantity and the term are fixed in a salam sale of food, there is no harm.

Al-Aswad (may Allah have mercy on him) was asked about a salam sale of food. He said: There is no harm if the quantity and the term are fixed.

Sa'id bin al-Musayyib (may Allah have mercy on him) said that in a salam sale, do not delay beyond the fixed term and do not hasten it, in order to collect a larger sum from your counterpart or for him to give you a smaller sum.

Sayyiduna Ibn Umar (may Allah be pleased with them both) saw no harm in making a salam sale of food with a fixed quantity and for a fixed term, so long as it is not in standing crops or in dates before their soundness becomes evident.

Sayyiduna Ibn Abi Awfa (may Allah be pleased with him) said: We used to make salam sales in wheat and raisins with the Nabataeans of the people of Sham while the Messenger of Allah (peace and blessings be upon him) was among us.

Sayyiduna Jabir (may Allah be pleased with him) said that salam in ghee is with a fixed quantity and a fixed term.

Abu Maysarah used to make salam sales in wheat.

Kulayb said: I asked Sayyiduna Ibn Umar (may Allah be pleased with them both): A man comes to us and makes a salam sale of wheat for a dirham for a fixed term, on the basis that each jarib (a measure) of wheat is one dirham and two jaribs of barley are one dirham (what about this?). He said: That is very good.

Sayyiduna Ibn Umar (may Allah be pleased with them both) said that if the measure and the term are fixed, then there is no harm in a salam sale.

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) saw no harm in making a salam sale in anything for a fixed term, except animals.

Muhammad bin Abi al-Mujalid said: Abu Burdah and Abdullah bin Shaddad differed about the salam sale, and they sent me to Sayyiduna Ibn Abi Awfa (may Allah be pleased with him). I asked him and he said: We used to make salam sales in wheat, barley and raisins in the time of the Prophet (peace and blessings be upon him) and of Sayyiduna Abu Bakr (may Allah be pleased with him), and we do not know whether his associates had any of it with them or not.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: I bear witness that the guaranteed salam for a fixed term is something Allah Almighty has made lawful and has permitted. Then he recited this verse: "When you contract a debt for a fixed term, write it down." [Al-Baqarah: 282].
