It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "The example of a believer is like that of a wheat plant, which sometimes bends down and sometimes stands upright, and the example of a disbeliever is like that of a pine tree, which always remains standing straight until it falls down, while it has no awareness at all."
