A: All praise is due to Allah Alone, and peace and blessings be upon His Messenger, his family, and Companions. (Part No. 5; Page No. 158) Firstly: It is not permissible for a man to shave his beard off if his parents ask him to do so, as shaving it off is Haram (prohibited). A Muslim should not obey anyone in something that involves disobedience to Allah.
Secondly:
If a man is forced to shave his beard off, because if he lets his beard grow this may result in him getting killed, one of his body parts will be cut off, he will lose the use of one of his senses, such as hearing or sight, or anything else like that, then it will be permissible.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
