We can see many reports of people reporting seeing Jesus and Mary and many other miracles like the Fatima sun miracle in 1917 in Portugal when people saw solar rays changing colour.
So when I read this these, I am sure that it is shatan. But it's troubling me because I have not heard in hadith saying shatan does miracles to fool other religion's peoples. I thought shatan does things to Muslims only. Can somebody please explain if this is done by shatan only?
