Narrated to us Abu Bakr ibn Abi Shaybah: narrated to us Abdullah ibn Numayr and Muhammad ibn Bishr, they said: narrated to us Zakariyya ibn Abi Za'idah, from Sa'd ibn Ibrahim: narrated to me Ibn Ka'b ibn Malik, from his father Ka'b, 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 wind bends it and lays it down one time, then straightens it another time, until it becomes dry and ripe. And the parable of the disbeliever is like that of a firmly rooted cedar tree on its base; nothing bends it, until it is uprooted all at once."
