“I
certainly
know people of my nation who will come on the Day of
Resurrection
with good deeds like the mountains of Tihamah, but Allah
will make
them like scattered dust.” Thawban said: “O Messenger of
Allah,
describe them to us and tell us more, so that we will not
become of
them unknowingly.” He said: “They are your brothers and from
your
race, worshipping at night as you do, but they will be people
who,
when they are alone, transgress the sacred limits of Allah.”
Sunan Ibn Majah Book 37, Hadith 146
