I don't know. Good catch. It would be hard to take that literally these days. It could be symbolism.
In the past, where it occurred humans were riding horses.
It was an everyday mass activity by a lot of humans.
The Holy War proves itself in human life that around the era of chosen reasoning to go to war, maths and science and cosmological studies had re emerged and began being re applied in the Muslim community. And the history of causation is the effects of radiation fall out, that changes the brain/mind and imbalances its rational ability to use human rationale.
Which is one of the warnings stated about radiation science.
The Shroud of Turin proved that a later day same irradiation fall out attack on human males occurred and it also attacked the animal lives...the same as the UFO ground attacks in modern life also have proven that exact circumstance.
And it is why they went to Holy War to stop the Temple and pyramid technology/sciences, which in the olden days was transmutations of metals, but they still were using radio wave transmitters that were like a power plant to force conversion and to transmute.
Why life was attacked by fall out conditions.
And it is apparent that it was true.
Hence spiritual teachings, healing of the conscious mind, spiritual truth was practiced and taught and applied about human conditioning to be loving, kind and caring and to love all of humanity no matter what belief you owned about Holy land or personal DNA.
Historically the reason for changed DNA is nuclear separate historic ground attacks in country variations.
Humans have fought for such a long time to gain a moment in their lives to tell their own truth for self and life continuance. Why don't you scientist agree with us?
The answer, because of human greed.
