Matthew 21:20-22

20And when the disciples saw [it], they wondered, saying, How immediately is the fig-tree dried up!

21And Jesus answering said to them, Verily I say unto you, If ye have faith, and do not doubt, not only shall ye do what [is done] to the fig-tree, but even if ye should say to this mountain, Be thou taken away and be thou cast into the sea, it shall come to pass.

22And all things whatsoever ye shall ask in prayer, believing, ye shall receive.
