However if you say something and then you also ask for...
However if you say something and then you also ask for forgiveness for that and if in asking forgiveness, you show your bravery and courage, then definitely a minor mistake would not be transformed into a major issue and as it is said that you would have immediately put out the flames with that (small) glass of water. However if that same fire was to spread to all other areas then even a large number of firemen would not be able to come and put out the fire and calm the situation!
This is the same within families as if an inappropriate action is done, if either side was to ask forgiveness for what had happened, then the incident would end right there. If this was not to happen, then the smallest things would turn into a major issue which may end up destroying the family! Does the person who is not ready to ask forgiveness think himself to be infallible?
Without doubt, everyone (with the exception of those who have been kept free from sins - the Prophets and the Ahlu'l Bayt) make mistakes. Therefore, if a person commits an error, then his asking pardon and forgiveness for his acts is actually proof of his greatness and excellence!
Asking for Pardon is a Sign of the Spiritual Expanse of one's Heart Do those who have little patience, a spiritual constriction in their hearts and do not possess the trait of a spiritually expansive heart assume that by asking pardon and seeking forgiveness that they are lowering their status!? Obviously, they are negligent of the fact that asking pardon actually proves the greatness in their character and personality and grants them a high nature!
My belief is that if we are truly impartial and equitable in regards to an issue - even in trivial things, and if in the face of the other person, no matter who he is - either a common person (who does not know the teachings of the faith) or one with knowledge - if we were to ask forgiveness (when we make a mistake), then this would be the key to a healthy life. Therefore, this act of apologizing is actually one of the valuable ethical traits.
As for the second issue - and this is something which also takes greatness of character and a spiritually expansive heart to carry out - it is to accept the apology of another person. If a person comes to you and asks to be forgiven, then one must accept the apology.
