Moderation is eliminating or even lessening extreme to some extent in every matter.
For example lying to someone in serious conversation is considered as something
wrong but in light conversation where we lie in joking manner, we don’t consider it as
wrong. Although lying is wrong in both cases. Sometimes we do ignore some bad
things cause they were done jokingly, and only consider it bad when done seriously.
The Prophet Muhammad (peace be upon him) once asked a companion: “(Is it true)
that you fast all day and stand in prayer all night?” The companion replied that the
report was indeed true. The Prophet then said: “Do not do that! Observe the fast
sometimes and also leave (it) at other times. Stand up for prayer at mypher and also
sleep at night Your body has a right over you, your eyes have a right over you and
your wife has a right over you”
