It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that he heard the Prophet (peace and blessings be upon him) saying to his Companions (may Allah be pleased with them): "Do not make your souls afraid" or he (peace and blessings be upon him) said (with the word 'al-anfus'): "Do not put the souls into terror." It was said: O Messenger of Allah (peace and blessings be upon him)! By what do we make our souls afraid? He (peace and blessings be upon him) said: "By debt."
