speaking lies

Q: Sometimes I secretly replace my wife's money from her purse with a bigger amount. For example, if she had R50, I take the R50 for myself and replace it with a R100 without her knowing in order to surprise her. When she comes to know of a bigger amount, I lie to her and tell her it was miracle that took place from the side of Allah. It really pleases her when she hears stuff like this, miracles etc. 

My questions are:

1. Am I guilty of the sin of lying?

2. By me replacing her money with a larger amount, is this regarded as Ribaa?

Q: I have committed a very big sin. I am really ashamed. And I am very much disturbed. I took hold of a Quraan and lied. The Quraan was in my hand and I lied. I was very much scared. Please help me and tell me how can I repent?

Q: I lied to my parents, my family, husband, his family and others that I did not love anyone before marriage. My husband found out but I denied it because I truly love my husband and my daughter. I did not want to lose them, is it a sin to lie like this? Will Allah forgive me? Will Allah help me?

Q: Is it ok to lie in order to save yourself from trouble if what you are doing is not sinful at all but only looked down upon because of culture? If so or if not can you please provide an example?

Q: I am an engineer. I did manipulate my resume to get a job and I have experience in that job but I added no. of years experience in my resume because companies usually looks for no. of years experience. But I resigned from that company because I felt guilty and confused about haram or halal. On my previous company I did my work very well and I am a hard worker too. Is manipulating the resume is haram? If it is, then what about making money through that job and spending it for my family and my entire life? From last one year I don't have any job and i got no. of job offers with the previous resume and I rejected it. But this time I am so confused because in one place I saw it is fine if your giving 100 percentage to the company but there is no authentic sources. Now I got a offer letter and confused about it.

Q: When I was about 11 or 12, my father lost his job. I was very sad but then he got a job in another country. I was very happy to go to my country again after 4 years of war so I woke up one day and told my uncle that I dreamt that dad got the job but I didn't really dream it. I was very stupid so he went for the job and stayed living alone for 4 years and now I regret it. I didn't know how life goes and now I feel very bad but at the same time I feel very shy to go up to him and tell him that I lied to you 4 years ago, like he's my father so I don't know what to do.

Q: If a Muslim tells a lie intentionally or unintentionally or by mistake or he breaks an oath if he can't keep it or breaks it intentionally or because he forgot or he does not pay someone's amanat will he remain a Muslim?

Q: Me and my wife are currently separated but not divorced. We have been separated for 6 weeks now. My questions are as follows:

1. How long are we allowed to be separated before our marriage will be null and void?

2. My wife wants a fasagh, however I want to reconcile. The problem was that I borrowed money from a friend and never told my wife and she only found out afterwards that I borrowed money from a female... Is she allowed to be granted a fasagh on the basis of mistrust and lies?

3. If she insists on a fasagh and I dont want to because I still love her and for the sake of our children, can the Alim force her to give me a chance even though her parents don't want her to take me back?
