It was narrated that Abu Dharr said: "The Messenger of Allah said: 'There will be people among my Ummah (nation) after me who will recite the Qur'an, but it will not go any deeper than their throats. They will pass through Islam like an arrow passing through its target, then they will never return to it. They are the most evil of mankind and of all creation.' " 'Abdullah bin Samit said: "I mentioned to Rafi' bin 'Amr, the brother of Hakam bin 'Amr Ghifari and he said: 'I also heard that from the Messenger of Allah.'"
