•► " They ask you , [O Muhammad], about the Hour : when is its arrival ?Say , " Its knowledge is only with my Lord . None will reveal its time except Him . It lays heavily upon the heavens and the earth . It will not come upon you except unexpectedly ." They ask you as if you are familiar with it . Say , " Its knowledge is only with Allah , but most of the people do not know ." --
[The Qur'an, Surah Al Aa'raaf (7):187]
