Washing clothes in a washing machine

Q: Please can you tell me if all my laundry clothes are pure or not. I did a washing machine laundry in a western washing machine with 4 rinse and spins but one item which was soiled with sweat left residue of possibly the sweat itself or the washing powder/conditioner. I am really worried now and I feel as though all my other clothes won't be clean and then my namaz won't be accepted or that through wetness I may be transferring impurity everywhere. It's difficult to do the whole laundry again as it takes over an hour to wash it and don't want to endure problems with family memebers as to why i am rewashing clothes. I'm worried because although none of the clothes had any major impurity I think, there maybe possibility there was. Please advise if my laundry clothes are pure or not.

Not following a mazhab

Q: People in my area follow different imams and they claim that their act is correct and perfect than the other. They also say to me that you follow one imam only, reply to them that I will follow what is there is in Quran and sunnah (hadith-sahih + sanan+ other books-with references) irrespective of following one imam and making sects (as said in Quran" Vo ati ullaha Vo ati ur rasula") and they don't fluctuate w.r.t time as it is followed by prophet in times. Am I correct in this case of following Quran and hadith(also includes imams +sahaba+mufti+fuqaha) or following a single imam?

Changing one's surname

Q: I was born without a father. He took off before I was born. I only saw him once, I was 16 years old then. No financial whatsoever. My mother raised me alone. They were married but the marriage was annulled when I was 8. We live in the Philippines where Democracy is the law. We are Moslems but because of my father's absence while I was growing up, I was given a surname that is of my mother's. I know its not permissible but I was a kid back then. Now I have my own family. I need to file for my children's correct birth certificate. I ask authority that if its allowed I'd have my husband's name and last name as their middle name and surname respectively. However, our government doesn't allow things like that. I know in Islam it is not permissible to attach the surname of your mother to the names of your children. But our government requires us. Now, my problem is, if I have to attach my surname as their middle name, am I somehow commiting a sin? Using my wrong surname(my mother's last name) as their middle name is a sin already but the fact that it is a wrong surname makes it even more complicated. I cannot just change my surname because of some pertinent documents. If I do, my children might not be able to receive whatever our government has to offer them thru me. Should I just let them use my surname as their middle name since even if I change it to my original surname (my father's), it doesn't make it right in Islam. Allah Ta'ala knows, I tried convincing them, citing that in Islam children are supposed to bear their fathers name and surname but they won't let me. Please help. I am going to send my kids to school but their records are not set right.

Women studying in universities

Q: I read your answer about women studying in universities. You say its not good? Why? Islam never stopped womens rights. Me and my friends study in university in abaya. We never talk to boys unless its necessary. But you are saying it is bad, it is haram. So that means women should not go to universities? I know many people who bound their women in houses and don't allow them to go for education. I am very sad after reading it. That means women don't have right to go and study if she likes to study and men can do anything? Why? Men can marry the girls too who are not Muslims?
