Beards and Moustache

Q:

1. Can I grow my beard up to my chest. Would it be better to grow upto the chest or only one fist.

2. Which colour safa is sunnat?

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?

Q: Which one is more close to Sunnah shaving the mustache with a razor or trimming it with scissors or trimmer?

Q: 

1. Is it sunnat, waajib or fardh to keep a beard?
2. When I keep a beard it only troubles me. I keep scratching, rubbing (even in salaah), and applying lotion. Is it permissible for me to shave?

Q: Could you also inform me where does the beard starts from? I often face this dilemma when cutting my hair (head)?

Q:

1. Did Nabi (Sallahu Alaihi Wasallam) ever trim His Blessed beard?
2. If not, how is a fist lenght beard an emphasized Sunnah?
3. Which is more rewarding; a trimmed fistful beard or a completely untrimmed natural beard?
4. On what basis is it sinful to trim (not shave) the beard less than a fist length (and not resembling the non-believers)?
5. Is there any Narration that directly prohibits trimming (not shaving) the beard less than a fist length?
6. Is Miswaak, wearing a turban on the same level as Sunnah, higher or lower, in comparison to having a fist length beard?
7. Is a person sinful if he does not use a Miswaak or wear a turban?

Q: Is it allowed in Islam for a male to neaten the beard (NOT CUT) while it is still growing to a fist length (Not yet a fist length) as I am still in my teens and my beard has become extremely wild which is not exactly 'in my opinion' what Islam teaches. To me Islam teaches dignity in portraying ourselves to promote Islam rather than be seen as primitive and uncouth. 

Q: I would like to know from which point on the face should the beard be grown to a fist length. Example, should it start from the top of ear, or from under the earlobe, or mid ear etc. Also, is keeping the beard to a fist length fardh or sunnah?

Q: What is the shar'iee beard length and how is this proven from the Ahaadith?
