Zuhayr ibn Harb narrated to me: Bishr ibn al-Sarri and ʿAbd al-Rahman ibn Mahdi narrated to us, they said: Sufyan narrated to us, from Saʿd ibn Ibrahim, from ʿAbd al-Rahman ibn Kaʿb ibn Malik, from his father, who said: The Messenger of Allah, peace and blessings be upon him, said: "The parable of the believer is like that of a tender plant in a field; the winds bend it, toppling it one time and straightening it another, until its appointed time comes. And the parable of the hypocrite is like that of a firmly rooted cedar tree, which nothing affects until it is uprooted all at once."
