Harith ibn Rab'i
Muhammad's era (610-632)
Harith ibn Rab'i narrated:
- A funeral procession passed by Allah's Apostle who said, "Relieved or relieving?" The people asked, "O Allah's Apostle! 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."
