It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The example of a Muslim is like that of a crop; winds constantly blow over it and keep it swaying, and calamities also keep coming upon a Muslim. And the example of a hypocrite is like that of a pine tree, which does not move by itself, but is uprooted all at once.
