Narrated Anas bin Malik:
"The Messenger of Allah (ﷺ) was brought a dish with unripe dates on it. He said: The parable of a goodly word is that of a goodly tree, whose root is firmly fixed, and its branches (reach) to the sky (14:24 & 25).' And he said: 'It is the date-palm.' And the parable of an evil tree uprooted from the surface of the earth, having no stability (14:26). He said: 'It is the colocynth tree.'" (ES)
