How do angry people behave when afflicted with a trial, and what is an example of a lack of patience with a trial, such as the case of Mus'ab ibn 'Umayr?

The nature of this worldly life is trial, and a believer must be patient and adopt patience as a means to guarantee reward. It was not reported that Mus'ab ibn Umayr despaired; rather, he endured imprisonment. The story of the woman weeping at the grave illustrates that true patience is at the first shock. People facing calamities are categorized into four levels: discontent (which is blameworthy), patience (enduring hardship), contentment (accepting divine decree and destiny), and gratitude (the highest level). One should inquire about examples of patience and contentment and emulate them, and avoid seeking instances of human despair and weakness, as there is no good example in them.
