Musannaf Ibn Abi Shaybah 37131 — Reports from our Prophet

It is narrated from Sayyiduna Ka'b (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) said: "The likeness of the believer is that of a tender crop: the winds move it, sometimes bending it and sometimes straightening it, until it turns yellow. And the likeness of the disbeliever is that of a pine standing upright on its root in the ground: nothing can move it until it is uprooted all at once."
