Volume 8, Book 73, Number 165:
Narrated Ibn ‘Umar:
Allah’s Apostle said, “Inform me of a tree which resembles a Muslim, giving its fruits at every sea –
son by the permission of its Lord, and the leaves of which do not fall.” I thought of the date-palm
tree, but I disliked to speak because Abu Bakr and ‘Umar were present there. When nobody spoke,
the Prophet said, “It is the date-palm tree” When I came out with my father, I said, “O father! It came
to my mind that it was the date-palm tree.” He said, “What prevented you from saying it?” Had you
said it, it would have been more dearer to me than such-and-such a thing (fortune).” I said, “Nothing
prevented me but the fact that neither you nor Abu Bakr spoke, so I disliked to speak (in your pres –
ence).”
