Bukhari Collection: ::Book Number 4:: Hadith # 784
Narrated Jabir bin `Abdullah:The Prophet 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 descended (the pulpit) and embraced it while it continued moaning like a child being quietened. The Prophet said, "It was crying for (missing) what it used to hear of religious knowledge given near to it."
