The Messenger of Allah (sal Allahu alaihi wa sallam) said: “When the son of Adam wakes up in the morning, all of his body parts humble themselves in front of the tongue and say, ‘Fear Allah with regards to our rights! Our wellbeing depends on you. If you remain upright, so shall we. If you become crooked, so shall we.’” [Ahmad]
We have been warned against uttering something callously without contemplating its consequences.
How many women have been divorced by their husbands merely due to the tongue! A man falls into an argument with his wife and she begins to repeatedly challenge him, “Divorce me! I challenge you to divorce me! Divorce me if you are a man!”
He orders her to be silent, perhaps shouts at and scolds her. When things get out of hand, he destroys his own household by eventually telling her that she is indeed divorced.
For this reason, the Prophet (sal Allahu alaihi wa sallam) advised that when a person gets angry, he should observe silence, because he otherwise will not be able to control his tongue.
A WORD that comes out of your Mouth is POWERFUL than a BULLET that comes out a GUN.
