Sayyiduna Uqbah bin Amir (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) saying to his Companions (may Allah be pleased with them): "Do not bring fear upon yourselves." It was said: O Messenger of Allah! With what would we bring fear upon ourselves? He (peace and blessings be upon him) said: "Debt."
