Imam Ja’far As-Sadiq (as) narrates that Imam Hasan (as) was on his way to Mecca for Umrah, the Minor Pilgrimage. One of the sons of Zubair was travelling along with him. They rested for a while under the shade of a tree. The son of Zubair said, “How I wish, the tree was bearing fruits that we ate them!”
Imam Hasan (as) asked him, “Do you really want to eat the fruits?” The son of Zubair said, “Yes! O Master! I have a desire to eat the fruits.”
Imam Hasan (as) raised his hands towards the sky and prayed. Lo and behold! The tree was instantly loaded with the fruits! One of the camel drivers said, “What a magic that fruits appear on the barren tree!”
The Imam (as) said, “Don’t call it magic. The Prophet (S)’s son’s prayer has been answered by Allah!”
