Crows hold funerals for their dead.
1400 years ago people thought that only humans hold funerals for their dead. However today we know that this is false, crows hold funerals for their dead.
Someone is dead. There's a body, attended by a number of concerned and watchful figures, all in black.
The lifeless corpse belongs to a crow, and the dark-garbed group congregating nearby is a gathering of its fellow crows, sometimes referred to as a "murder." That name is particularly apt in this case, as murder is what holds their attention. Their vigilance over a dead crow serves a purpose - one that's a matter of life and death, according to a new study in the journal Animal Behavior. By sticking close to a crow that was killed, other crows may improve their chances of learning about predators they need to avoid.

Today we know that crows hold funerals for their dead. However this was portrayed in the Quran 1400 years before it was discovered.
[Quran 5:31] Then Allah sent a crow digging the ground, to show him how to cover his brother's corpse. He said, "Woe to me! I was unable to be like this crow, and bury my brother's corpse." So he became full of regrets.
How could an illiterate man who lived 1400 years ago have known that crows hold funerals for their dead?
