Leaning and eating

Q: I heard an Aalim say that the Kitaabs of hanafi fiqh state that there is no problem with eating while leaning.

1.What does this mean?

2. The Hadith that mentions we must not lean and eat. What type of leaning does it refer to?

Protection from jinn

Q: My question is that one of my friends gave me two copies of letters of Holy Prophet (Sallallahu Alayhi Wasallam) to the jinnaat for protection purposes because once a tragedy happened to me. One copy is translated and the other is not. One's Arabic words are different from the other. Similarly there are some Arabic duas which we learnt but the same are quite different or some extent different from what we read elsewhere. Is it permissible to recite these duas?

Inheritance

Q: My father died and he left a house. This housed is co-owned with his two brothers. My uncle went and sold the house and it's front land. The problem is that the essence of the purchase of the house was filled with problems like forcing people to sell their rights to the house. Secondly, we don't know yet whether my uncle who sold the house also sold the house of someone else and included in the inheritance that will be given to us. My uncle has sold their land too and gave them $50,000 however, that family are saying that their house has been sold and is in the money in the money that is given out to us. We have informed this to our uncle and he is rejecting all of this and is saying that he has not sold their house. Now the inheritance that will be given to us, we don't know what to do with it. Is it halal for us? Do we have to make the money halal by giving out charity? Or is it forbidden for us to consume the money and we should give out the whole money onto sadaqah.
