Is it bad to spend money dedicated to God

Hi, yesterday I gave my sister money to put into my bank account through cardless deposit when she walked to the shopping centre, I can't go at the moment due to endometriosis pain. So I asked my mom today of we could drive to the bank, mind you my sister hasn't given me the money. My mom is ready to go to the bank and my I asked my sister for my money and she doesn't remember where her purse is (my sister is irresponsible with things sometimes). We all tried looking for it but couldn't find it so my mom told her to give me the money from her pile dedicated to God and when she fines her purse replace the money with the money I gave to her yesterday. Her purse has been found, but the money from her pile is already in my banck account. Im a little paranoid now and wondering if it's still wrong to spend the money.

Context: If anyone is wondering why I need the money on my card it's because my friend's birthday is coming up soon and found her a gift online but I had no money on my card.
