Silsilat al-Ahadith al-Sahihah

Sayyiduna Awf bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "So avoid such sins which are not forgiven," and in another narration: "the sins for which there is no expiation." Whoever commits a breach of trust, that thing will be brought with him on the Day of Resurrection. And regarding the one who consumes usury (interest), it is warned that whoever consumes usury will be raised on the Day of Resurrection as insane and bewildered because of it." Then the Prophet (peace and blessings be upon him) recited the verse of the Qur'an: "Those who consume usury will not stand except as one stands whom the devil has driven to madness by (his) touch." __QUR_N__
