It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever places his trust in a believer and he cheats him, that cheating of his is usury (riba)."
Musa bin Umayr al-Qurashi has been criticised; Ibn Adi said: most of what Musa bin Umayr narrates is not corroborated by the trustworthy narrators. Its meaning has also been narrated from Ya'ish bin Hisham al-Qarqisiyani from Malik, with disagreement over its chain, and that is weaker than this.
