Musannaf Ibn Abi Shaybah 24416 — Paying in advance (salam) for silk

Al-Faza' said: I said to Sayyiduna Ibn Umar (may Allah be pleased with them both): What do you say about al-saraq? He asked: What is al-saraq? I said: Silk, or pieces of silk. He said: O people of Iraq! You give bad names. Have you not named it shuqaq al-harir (pieces of silk)? I said: It has a price in the market. We buy it at that price and then sell it onward, on credit until the stipend is paid, at a higher price. He said: When you have bought it and taken possession of it, then sell it however you wish.
