Keeping the name "Wahdaan"

Q: I was looking up names for my newborn baby boy and came across the name Wahdaan (meaning shows up as peerless, unique and singular). One of our good friends suggested that names like Ahad, Wahid, Wahdaan should not be kept for babies as only Allah Ta'ala is deserving of those names and humans should not be named with such names. Should I go ahead with the name Wahdaan or do you advise against it? Your help and clarification would be really appreciated.

Living in a hostel

Q:

1. I live in a hostel and I have to share bathrooms with kaafirs. My question is I have doubts about the purity of the bucket but I don't see any kind of visible najaasat. What I used to do was I fill up the bucket till the water overflow and I use the water from that bucket without throwing it and recently I have seen on this website that you have to throw the water to make that bucket pure. So was I impure all the time and do I have to repeat my prayers.

2. My room mate uses anti anti-perspirants like powder and I see particles on the floor and I don't know whether that powder is made from halaal sources or not. My leg touches those particles which is very much less than a dirham even after combining all the particles. Does my leg become impure and the places where I keep my feet also became impure? It was less than a dirham size.

Feeling happy about one's good actions

Q: Sometimes when we have done a good deed, or have said a good thing that is only for Allah's pleasure, we often feel good about what we have done, and sometimes these thoughts stay in our head for long. Please I want to know, is this associated with riya? Can my good deeds become invalid for this reason and how should I stop this "Self-thinking-Admiration" process. And also please can you help me with a link to download a book on riya in-depth. May Allah Reward you.

Marriage problems

Q: I want to ask you my condition related to Quran and Ahadith. Two years earlier my parents engaged me to guy who was morally, family wise, and Islamicly a noble person. But the only reason I couldn't get married to him is because of my parents ego.  A stamp paper of a plot in a very expensive area. Which a middle class person can't afford. They have agreed to write it in my mehr and would buy it for me later on along with 5o tola gold and 5 lac rupees. But my parents didn't agree. Everyone in the world questions me about my marriage but I am ashamed to answer as I have nothing to say plus I don't want my parents repo to be spoilt. The guy and his family is struggling very hard for me and the guy has debts too. Don't you think this is destroying my life? What does the Qur'an and Hadith say in this case? What should I do?
