'One of the things that Allah confided to Moses (AS) on the mountain is : ?O Moses, inform your people that those who are close to Me can only come nearer to Me by crying to Me out of awe of Me, and the best worship performed by My worshippers is restraint against committing what I have forbidden. Those who adorn themselves for Me have no better adornment than abstinence from worldly affairs in that which they can manage without.' Moses (AS) asked, ?O Most Generous of the generous, so what establishes them upon it?' He said, ?O Moses, as for those who come near to Me with crying from My awe, they are in the loftiest level which they will share with no one.'
