ANSWER:

Her husband is sinful for backbiting his wife and she must advise him to act like a man and stop backbiting her in front of others.

She must be tactful in her approach and become the one he seeks his tranquility in, in order to put a stop to this.

Husband and his siblings share everythin with each other,even the wrongs of their wives,his sister acts like she is their mother advising them about the wrongs of their wives etc, its like they want 2 share every details,husband can’t live without their advices,heard him telling his brothers the wrongs of their wives openly,calling everyday 2 one another constantly, gives me anxiety how 2 deal?
