Sayyiduna Ka'b bin Malik (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "The likeness of the believer is that of a tender plant of the crops which the winds keep bending, sometimes laying it down and sometimes straightening it, until his appointed time comes to him. The likeness of the disbeliever is that of a sturdy cedar tree standing stiffly upon its root; the winds cannot bend it, until it is uprooted all at once."
