A report is recorded about Imam Reza (a.s.) .
Harith Hamadani has narrated that we reached a dried up tree,
whose skin had fallen off. We saw His Eminence place his hand on
that tree and say: “O tree, become verdant and fructify.”
Suddenly we saw the tree turn verdant and its branches filled with pears. We ate those fruits and also took with us some of it. The following day,
also, we went to that tree and saw it verdant and laden with fruits
