Matthew 17:20 New International Version (NIV)
20 He replied, “Because you have so little faith. Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”
The passage about "Faith that can move mountains" are often looked at as a metaphor etc. In 975 AD in Egypt an event occurred that resembles the Jewish Holiday of Purim. (The Coptic Christians faced genocide at the hands of Muslims unless they could make this miracle happen). This event was consider to be a true historic event even by the Muslims of Egypt all the way until recent times (Text books listed as taking place all the way to 2010). However with the rise of the Muslim brotherhood and Muslim fundamentalism it is now officially denied.
