Picking up a lost paper

Q:

1. What rule of lost property should be followed if one sees a page with the Mubaarak Name of الله تعالى lying on the floor?

2. If one saw صلى الله عليه وسلم تسليما كثيرا كثيرا on a page, picked it up and because there was no immediate place available to leave it put it into his copy of القرآن الكريم, he then forgot about it until he went home to another country. What happens if he burnt it?

3. What happens in a similar situation where words are written in a foreign language (that one does not understand) on a page which is found lying on the Mataaf sharif and because of many carrying duaas he assumes that that is the nature of the page and does as mentioned above (returns home, burns it)?

Husband telling the wife to leave

Q: I am a 20 year old girl. I got married last year December. Recently my husband and I have been having some problems. He has told me to leave twice but from those two times I only left once which was last week Wednesday. I am currently at my father's house. My question is if my husband told me to leave, does that count as a talaaq?
