Sometimes I ask Allah to send sakinah/peace in my heart for something that I'm praying for & He sends it and I immediately feel at peace but sometimes when I ask for sakinah/peace again for the same thing because of uneasiness in my chest, I do not get it so I ask Him if the opposite is true (opposite of what I'm asking) and then I feel like at peace for the complete opposite happening. So here I am wondering if Satan can give us a false sense of peace to cause us distress etc because he knows what we're asking from Allah. How do I know what feeling is from Allah and what feeling is not?
I'm just really, really confused. Any sort of guidance will be appreciated.
