Sadaqah

Q: Last couple of months my wife is very sick and I would like to give out Sadaqa. My question is 1:-What intention I must make? 2:-Can I give this Sadaqa to poor Non Muslims?

Passing wind

Q: I have heard that passing wind being in the state of wudhu, breaks wudhu only if the wind has odour or sound. Otherwise wudhu remains valid. Is it true?
