Wife following her mazhab after getting married to a Salafi

Q: We follow the Hanafi school of thought. However, my daughter married and her husband is now saying that he is a Salafi. We have never heard about this before. They join salaahs when they travel, make tayamum if there is no water whilst they on the go. Also, they read salaah while in a moving vehicle and if they feel its dangerous to stop the car. She is young and scared. Can you please help me with advice. 

Giving up drugs

Q: I am a practicing Muslim, I don't miss my salaahs or daily Quraan but I just can't seem to shake off the occasional drug habit. I make dua everyday for help. What should I do?

Moving in ruku and jalsah

Q: In the Jalsa or Ruku in prayer, we have to stop for at least one Subhanallah, but do we have to sit in Jalsa completely motionless, or is it okay if we sit for at least one Subhanallah but in that time our arm moved a little or our leg(s) moved a little? The same question is for Ruku too, do we have to be completely motionless, or is it okay that we be in Ruku for at least one Subhanallah but during that time we move a little? 

Muslim girl taking consent from her non Muslim father or brother before getting married

Q: I want to marry a woman who has become Muslim, but her family is kafir. Her father is divorced from her mother and has not lived with him for more than 10 years and she lives with her mother and younger brother.

In this case does the girl need to ask permission or have the consent of someone from her family (Wali) or can she marry me only with her own consent?
