Narrated by Ibn Umar:
The Prophet used to deliver his sermons while standing beside (or leaning on) a trunk of a Date Palm tree. When he had the pulpit made, he used it (the pulpit) instead (of the Date Palm tree). The trunk (of the tree) started crying/weeping (grieving out of love for the prophet) and the Prophet approached it, rubbing his hand over it (to sooth it and stop its crying/weeping).
Share if you have a heart. Ignore if you like to see trees cry, you sick **ck.
Update: The Mufti Council has issued a new fatwa which instructs Muslims to get rid of all pulpits in mosques and replace them with sentient trees. Follow the sunnah.
