Just out of curiosity, other than this Jewish story, is there any other evidence for Allah asking Muslims to kill and animal (or human) as a sacrifice?
I'm also curious if pre-Islamic Arabs sacrificed animals to the Gods?
As I understand it, most of the "sacrifices" were in actuality BBQ were everyone in the tribe came around and had a plate of meat from the best of the best cattle. The whole God thing was really just to get someone to pony up a free slab of good meat.
I'm not even certain how the Muslim festival became instituted
Accordng to the verses in the Qur'an its not even clear that any sacrifice of the son as in killing, was intended. The only dialogue is with reference to the son putting the forehead down, as we do in prayer, following the fathers announcement of his dream. When they pray [as I read it] they are told that they have believed a dream. This announcement [that it was only a dream] is their reward and they celebrate it by killing a lamb as they do [dabiha] for all celebrations.
It seems more like a don't act on your dreams story than a kill a lamb to replace your son story.
