It is narrated from Hazrat Abu Saeed (may Allah be pleased with him) that he heard the Prophet (peace and blessings be upon him) saying: "A people will emerge among you, and you will consider your prayers insignificant compared to their prayers, and your fasts insignificant compared to their fasts, but they will go out of the religion just as an arrow passes through the prey. A man takes his arrow, looks at its tip and sees nothing on it, then looks at its sinew and sees nothing on it, then looks at its shaft and sees nothing on it, then looks at its feathers and sees nothing on them."
