question #2 Sahih al-Bukhari 6512, Book 81, Hadith 101 : How does death serve as a relief for a believer according to Islamic teachings?

A funeral procession passed by Allah’s Messenger (ﷺ) who said, “Relieved or relieving?” The people asked,
“O Allah’s Messenger (ﷺ)! What is relieved and relieving?” He said, “A believer is relieved (by death) from
the troubles and hardships of the world and leaves for the Mercy of Allah, while (the death of) a
wicked person relieves the people, the land, the trees, (and) the animals from him.”
