Do not become too attached to material possessions; remember death can come at any time; show gratitude for what you have; remain humble despite your accomplishments or wealth; remember those who passed away before you even though they may have been better than you in character or deed .

This hadith, narrated by Sa'd bin Ibrahim, speaks to the impermanence of life and wealth. It tells the story of 'Abdur-Rahman bin 'Auf who was presented with a meal while he was fasting. He then recalled how his friend Mus'ab bin Umar was martyred, despite being better than him in character. He also remembered how Hamza, another friend who was even better than him in character, had been martyred as well. Abdur-Rahman then realized that worldly wealth had been bestowed upon them but they were given too much of it which made him fear that their rewards for their deeds may have already been given to them in this life instead of the afterlife. This realization caused Abdur-Rahman to weep so much that he left his food untouched. The main lesson from this hadith is that we should not become too attached to our worldly possessions because death can come at any time and our lives are fleeting and impermanent no matter how good we are or how much wealth we have accumulated on earth.
