Sayyidah Aishah (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) bought wheat from a Jew, fixed a time for payment, and pledged his coat of mail.
It is reported about Sayyiduna Ibn Abbas (may Allah be pleased with him) that he saw no harm in a pledge (rahn) and a surety (qabil) in an advance sale.
