Ibne Shahr Ashob has narrated from Dawood Neeli that he said:
I went for Hajj in the company of Imam Ja’far Sadiq (a.s.). On
the way, the time of Noon Prayer arrived. Imam (a.s.) said:
“Dawood, move out of my way, so that I may prepare for the ritual
prayer.” I said: “May I be sacrificed on you, how would you prepare
for ritual prayer in this dry desert?” He replied: “Keep quiet and
don’t interfere in this matter.” So I left the way and reached a dry
piece of land. His Eminence hit his foot on the ground. Cool water
gushed out from there. I and His Eminence performed ablution and
prayed the ritual prayer.
There was a dried up date tree drooping on the ground. While
walking the Imam (a.s.) asked: “Dawood, would you like to have
some dates?” “Yes,” I said. I saw him hit his hand on the tree and
shake it. He brought out dates from it and gave me to eat. Then he hit
his blessed hand upon and said: “Revert to your previous condition.”
The tree assumed its former condition
