Mark 11:22

As they passed by in the morning, they saw the fig tree withered away from the roots.

Peter, remembering, said to him, "Rabbi, look! The fig tree which you cursed has withered away.

For most certainly I tell you, whoever may tell this mountain, 'Be taken up and cast into the sea,' and doesn't doubt in his heart, but believes that what he says is happening; he shall have whatever he says.

Therefore I tell you, all things whatever you pray and ask for, believe that you have received them, and you shall have them.
