I heard Allâh's Messenger (ﷺ) saying, "There will appear some people among you whose (prayer) will make you look down upon yours, and whose Saum (fasting) will make you look down upon yours, and whose (good) deeds will make you look down upon yours, but they will recite the Qur'ân which will not exceed their throats (they will not act on it) and they will go out of Islâm as an arrow goes out through the game whereupon the archer would examine the arrowhead but see nothing, and look at the unfeathered part of arrow but see nothing, and look at the arrowfeathers but see nothing, and finally he suspects to find something in the lower part of the arrow." [6:578-O.B]
