Their is a famous sufi story about miracles that I read yesterday in Idries Shah's book.

One of the famous sufi, Rabia, once while cooking realized she did not have onions. She is supposed to have said - "I want onion" and there was spring of onion that fell from the sky. Seeing this people said, this is a miracle.

Rabia said, if that is miracle what is the fact that god created onion shops for us to get onions.
