Narrated Abu Huraira (Radi-Allahu 'anhu):

Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) said, "The example of a
believer is that of a fresh tender plant; from whatever direction the wind
comes, it bends, but when the wind becomes quiet, it becomes straight
again. Similarly, a believer is afflicted with calamities (but he remains
patient till Allah removes his difficulties). And an impious wicked person
is like a pine tree which keeps hard and straight till Allah cuts (breaks)
it down when He wishes."
