Sahih al-Bukhari Book 34, Hadith 48
An Ansari woman said to Allah's Messenger (ﷺ), "O Allah's Messenger (ﷺ)! Shall I make something for you to sit
on, as I have a slave who is a carpenter?" He replied, "If you wish." So, she got a pulpit made for him.
When it was Friday the Prophet (ﷺ) sat on that pulpit. The date-palm stem near which the Prophet (ﷺ) used to
deliver his sermons cried so much so that it was about to burst. The Prophet (ﷺ) came down from the
pulpit to the stem and embraced it and it started groaning like a child being persuaded to stop crying
and then it stopped crying. The Prophet (ﷺ) said,"It has cried because of (missing) what it use to hear of
the religions knowledge."
Some men came to Sahl bin Sa`d to ask him about the pulpit. He replied, "Allah's Messenger (ﷺ) sent for a woman (Sahl named her) (this message): 'Order your slave carpenter to make pieces of wood (i.e. a pulpit) for me so that I may sit on it while addressing the people.' So, she ordered him to make it from the tamarisk of the forest. He brought it to her and she sent it to Allah's Messenger (ﷺ) . Allah's Messenger (ﷺ) ordered it to be placed in the mosque: so, it was put and he sat on it.
Allah's Messenger (ﷺ) bought food grains from a Jew on credit and mortgaged his armor to him.
