Eating a piece of chocolate that one was supposed to give to someone else

Q: My one friend gave me a piece of chocolate and told me to give it to his friend who was sitting close to me but instead I ate the piece of chocolate. The friend who was supposed to get the chocolate didn't even know he was supposed to get it and the friend who gave the chocolate saw me eat it but didn't say anything. Do I have to repay the friend who was supposed to get the chocolate?

Doubting whether one read tasbeeh in sajdah correctly

Q: I was praying Fajr and generally at this time my brain cannot remember things well (just got up!). First, I am a non Arabic speaker so I have to deliberately pronounce well to avoid pronunciation mistakes. I was praying the second rakah of Fajr and I forgot whether I said Subhaana rabbiy al-a'laa correctly in the first rakah. I was not sure but I ignored this doubt and continued and not repeat Fajr. Did I do the right thing?
