Taqleed

Q: Concerning "the pen has been lifted and the ink has dried", what is this referring to? i.e. What aspects of destiny? I was of the opinion that dua can change destiny, but how does dua changing destiny fit into the qouted hadith?

I guess what i'm asking is:

1. What exactly has been written in ink? i.e. Is every action of every insaan written down?
2. Can dua change any of what has been written in ink?
3. If I make dua to change my destiny, is me making this dua written down? If so then is it not true that my dua hasnt really changed anything as it was already written that I would do this and my destiny would change? I just can't quite get my head around this, any light shed on the matter would be appreciated.

Q: Me and my family follow the Madhab of the Hanafi school of thought, however I came across an issue where there is a difference of opinion between the Shafi and Hanafi schools of thought.

Q: A friend of mine who was born in Pakistan had migrated to Indonesia. He has no intention of going back to Pakistan. Now, he has a family in Indonesia. He is asking is it right that he changed his mazhab because he don't want to be the only one different in his own house and the community. His wife is also a local there and his children are sent to the local madresa.

Q: A scholar who gives a legal opinion is rewarded for it, two rewards for the one who is correct and one reward for the one who erred. Therefore we say that all imaams are on the right path and can be followed. So why can't we follow these salafi ulama?
