Bite your tongue
Everything we say and do in life has consequences.
Just like throwing a stone into a pond, sends ripples across the water
affecting all around it. We are free to say and do as we choose but the
consequences of our words and actions are our responsibility.
How many times have hasty words been spoken making a wedge between once loving friends or spouses?
Sometimes we think something bad about a person and in anger or when
emotions are high, we make those thoughts vocal. If we could have
waited a little, these negative thoughts may well have been replaced
with more kindly ones.
To speak or act while in a state of anger is really a mistake. It is a
good idea to bite your tongue and wait until the next day. If the same
level of emotions are present, then speak out, but chances are you will
have forgotten why you were angry.
{The good deed and the evil deed cannot be equal.
Repel (the evil) with one which is better (i.e. Allah ordered the
faithful believers to be patient at the time of anger, and to excuse
those who treat them badly), then verily! He between whom and you there
was enmity, (will become) as though he was a close friend.} (Sura Fussilat 41:34)
