It is narrated from Sayyiduna Abu Sa'id al-Khudri, may Allah be pleased with him, that I heard the Messenger of Allah, peace and blessings be upon him, say: "There will emerge among you some people who will consider your prayer insignificant compared to their prayer, and your fasting compared to their fasting, and your deeds compared to their deeds. They will recite the Word of Allah but it will not go below their throats. They will go out of the religion just as an arrow passes through the hunted animal, cleanly passing through. If one looks at the arrowhead, he will find nothing on it; if he looks at the shaft, he will find nothing on it; if he looks at the feathers, he will find nothing on them; and the one who doubts in the sinew will wonder whether anything has stuck to it or not."
