Abu Hurayrah relates that Rasulullah (sallallahu alaiyhi wassallam)
said, "My Ummah were given five things for Ramadhaan which were not
given to anyone except them. For them, the smell from the mouth of a
fasting person is more sweeter to Allah than the fragrant smell of musk.
On their behalf the fish in the sea seek forgiveness for the fasting persons
until they break their fast. Allah prepares and decorates a special
garden in Jannah everyday and then says (to it), "The time is near when
faithful servants shall cast aside the great trials of the world and come to
you". In this month (for them) evil-minded Shaytaan is chained so
as not to reach unto those evils to which they normally reach during other
months besides Ramadhaan. On the last night of Ramadhaan they are
forgiven".
The Sahaabah R.A. thereupon enquired, "0 Messenger of Allah, is that last
night Laylatul Qadr? Rasulullah (sallallahu alaiyhi wassallam) replied, "No.
But it is only right that a servant should be given his reward on having
completed his service".
