It is narrated from Sayyiduna Miqdam (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) on the day of Khaybar declared several things to be forbidden, then said: "Soon a man will come who, sitting on his couch, will say: 'Hold fast to the Qur'an; consider only what you find in it to be lawful as lawful, and what you find in it to be unlawful as unlawful.' Beware! Just as Allah has declared some things unlawful, the Messenger of Allah (peace and blessings of Allah be upon him) has also declared some things unlawful."
