Sayyiduna Hudhayfah (may Allah be pleased with him) narrates: I asked, "O Messenger of Allah! The goodness upon which we are now, will there come after it any evil from which we should beware?" The Prophet (peace and blessings of Allah be upon him) said: "O Hudhayfah! It is obligatory upon you to adhere to the Book of Allah." Acquire its knowledge and follow the goodness that is in it for you.
