Spend your wealth on good causes while you are alive rather than leaving it behind when you die; even if only a small amount remains unspent after death.

This hadith speaks to the importance of spending one’s wealth in service to Allah. Abu Dharr came to visit Uthman bin Affan with a stick in his hand, and asked him what he thought about a man who died leaving behind wealth. Ka'b replied that if he paid his dues to Allah, then that was fine. Abu Dharr then raised his stick and struck Ka'b, saying that he heard the Prophet Muhammad say “I would not like to have this mountain in gold and spend it for the sake of Allah, and have Allah accept it from me, but leave behind six ooqiyah of it” three times. Uthman confirmed that he heard this statement from Prophet Muhammad as well. The essence of this hadith is that one should strive to spend their wealth on good causes while they are alive rather than leaving it behind when they die; even if only a small amount remains unspent after death, one should still strive to give away as much as possible during life so as not to miss out on any rewards from God.
