Q: My cousin wanted to know that keeping beard is compulsory for muslim men? Is there no excuse of not keeping it? If his wife does not want him to keep and she doesn't feel attracted towards her husband in beard then is it permissible to not grow beard. Because there are excuses for men if he doesn't feel attracted towards his wife in joint heavy big eyebrows then she can trim it for the sake of her husband. But why the same rule doesn't applies to a lady? Kya shariat se koi gunjaish nahi hai for not keeping beard?

Q: I am keeping a fist length beard Insha Allah as it is wajib. However I want to ask a question just out of curiosity regarding trimming the beard slightly shorter than a fist. Most Deobandi Ulama say it is Makrooh e Tahrimi, and if done continously it is a major sin. However in Shah Hakeem Akhtar Sahib's book it was written that to cut even a few millimetres of the beard shorter than a fist is GUNAH KABEERA (major sin)? So do you agree with Hakeem Akhtar sahib's statement?
