It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once some people were sitting with the Noble Prophet (peace and blessings be upon him). The Noble Prophet (peace and blessings be upon him) asked Sayyiduna Bilal (may Allah be pleased with him) to bring the dates that he had. When he brought the dates and the Noble Prophet (peace and blessings be upon him) saw them, he was surprised and said: "Where did these dates come from?" Sayyiduna Bilal (may Allah be pleased with him) informed that he had given two sa’ to get one sa’ of dates. The Noble Prophet (peace and blessings be upon him) said: "Return the dates that were ours."
