From Sahih Bukhari (Hadith 5643):
Narrated Ka`b:The Prophet (ﷺ) said, "The example of a believer is that of a fresh tender plant, which the wind bends lt sometimes and some other time it makes it straight. And the example of a hypocrite is that of a pine tree which keeps straight till once it is uprooted suddenly
