3. The crying of the stem of the date-palm tree in the Prophet's Mosque: Narrated Ibn 'Umar, that the prophet used to deliver his Khutba (religious talk) while leaning against a trunk of a date-palm tree. When he had the pulpit made and used it instead, the trunk started crying and the Prophet went to it, rubbing his hand over it (to stop its crying). (See Sahih Al-Bukhari, Vol.4, Hadith No. 783).
