[Taken from Sahih Bukhari from its 4th Volume and Hadith No. is 784]
The Prophet Muhammad (Sal-allahu-aleihi-wasallam) used to stand by a tree or a date-palm on Friday.
Then an Ansari woman or man said. "O Allah's Apostle! Shall we make a pulpit for you?" He replied, "If you wish." So they made a pulpit for him and when it was Friday, he proceeded towards the pulpit (for delivering the sermon).
The date-palm cried like a child! The Prophet (Sal-allahu-aleihi-wasallam) descended (the pulpit) and embraced it while it continued moaning like a child being quietened. The Prophet (Sal-allahu-aleihi-wasallam) said, "It was crying for (missing) what it used to hear of religious knowledge given near to it."
Narrated by Jabir bin Abdullah (Razi Allah Anhu) and undoubtly this was a miracle.
