Removing impurity from countertops

Q: What is the best way to remove impurity from countertops? I had some wet impurity on a part of the countertop a while ago and it dried and nothing was visible, but the impurity itself was not visible. I spilled some water over a majority of the countertop (I could not cover the entire thing in water, as the water would have spilled over the sides), and then wiped it dry with tissue. The countertop is made of wood with a resin top however some of layers have come of so some wood is visible (the impurity was not on the wood parts, but the water I spilled on the impurity did get to the wood). Is this counter top pure? If not how do I clean it (note that impurity mixed with water has touched most of the countertop and since we make wudu/wash our hands here, no doubt it has transferred to a whole bunch of places). How do I take care of this?

Helping one's husband to stop being rude

Q: I need to know how to help my husband to stop being sarcastic and rude to everybody (his family, my family, close friends, my kids and I). His family even complains to me about how rude he is. I really don't know what to do anymore because it is affecting the way my son speaks as well. Do I take him to a therapist, Moulana?

PS: He doesn't see anything wrong with himself

Not allowing one's step son on one's property

Q: My husband has a son from his 1st marriage, he is 17. When we got married we used to see him at the weekends but then that stopped as it all went to court. Over the last year he made contact with my husband and they see each other every few weeks. Now his son wants to move in with us. I don't have an issue if he comes to visit but I am not comfortable with him moving in as I have a daughter from my previous marriage. She has not reached puberty yet but is 12 and will do soon.

My husband is adamant that he moves in with us. I want to know where I stand Islamically in this. My husband moved in with me into my property which I owned before I married him. My husband does own a property but his father and brother reside there.

Agent taking a commission

Q: My company arranges business agreements between two parties. According to the business agreement, the first party pays money to our company for the second party that gives service to the first party. Our company acts as a business agent and takes commission from the money given to us as fees for the second party without telling the first party but with the permission of the second party who already worked with us.

Also, we take another fee from the first party while telling them that it is our service fee for arranging the business agreement with the second party and it is a clear dealing.

My question is about the commission that we take from the second party fees without notifying the first party (payee) is halal or not? Because this commission is the main source of income for my company. If this commission is not permissible then the salary I take from the company is halal or not? 

Giving up porn and smoking

Q:

1. I have an e-cigarette. It is like an alterative to a cigrette and I've got lots of different types and spent alot of money on them but I want to stop it completely. Should I throw them away and go against my nafs?

2. I am a younster with hormones and I used to make accounts to watch naked women perform acts. Each time I had the urge I'd make a new account. Should I leave the accounts and ask for forgiveness and not go back to the accounts even if the accounts are there and not getting used? Will I be sinful everyday if the accounts are not there because I don't know how to delete them.

Inheritance

Q: My mother has only four daughters and no son. In preparing her will, my father and the four daughters are her primary heirs. She also has two sisters and two brothers. Are they entitled to an inheritance from her? If so, what will the distribution be among all her heirs?

Women cutting their hair

Q: Are women allowed to cut their hair? I heard some scholars say that this is not permitted because it is an imitation of men or the Kuffar. However, doesn't what is and isn't imitating men change with culture/times? Nowadays nearly all Muslim women cut their hair, and women cutting hair is considered normal in my culture (Turkish) and not all an imitation of men. Not to mention long/heavy hair is very difficult to maintain, and hard to cover fully when wearing a Hijab. So as long as the haircut does not imitate the Kuffar and is still long (not imitating the men), then is it permissible? If not, what is the proof of this?
