A:
Whoever
shaves his beard, lets his moustache grow and becomes negligent in his duties towards his family and relatives should be advised to stop that. He should be directed to do what is obligatory upon him (Part No. 12; Page No. 377) and he should be warned against the sins he commits. If he accepts the advice, that will be good; however, if he persists in neglecting his duties and in committing abominable acts, Allah (Exalted be He) makes it permissible to abandon him. Perhaps this will stop him.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
