 Assalam u Alikum. Words causes damage to your soul and this damages can`t repair by anyone , anywhere except Allah

Do you feel how painful if a person is cut through knife? but do you know what is more painful than this? to attack someone with your harsh words.Words are sharper than knife. Physical damage somehow heals but injured soul will never repair like a mirror.Words could not get off one`s back, harsh words cut a person into many pieces everyday and every night.

Holy Prophet ( PBUH) said that,

"A person could never be a believer , if others are not protected by his hands and tongue" 

Think hundred times before saying something because words are like arrows , once they are out of the bow then you become helpless. Words are your slave but once they are out of your mouth then you became the slave of your words.

Allah loves His creation , He fixes their rights that is Hukook ul Ibad. He will forgive you in those matters that are concerned with Him but will not forgive the violation of anyone's rights.

Holy Prophet(PBUH) said that,

"Allah will never forgive the violation of anyone`s rights until they forgive you"

Anger is prohibited in Islam because it makes your senses weaker, you lost the power of thinking and understanding. You forget that to whom are you talking, how are you talking and what the words are you using. You just want to take out all the frustration to normalize yourself but in this process how many hearts are broken and how many eyes are filled with tears.

Holy Prophet (PBUH) said that ,

"The best among you are those who are best in their character (ikhlaq)"

When ever anger dominates you, the best practice is to remain silent and move from your place, when you cools down then analyse the situation. if mistake is yours then try to compensate and have a few words with them , when you exchange your thoughts then you get to know that no one is wrong but the problem is of understanding.
