Re: Quran is full of moral stories and metaphors
what does Arabic ‘Juz’an’ represent? Put part of them (birds) on each hill, means they have to slaughtered and separated into pieces. If we look at starting of the verse where Ibrahim (AS) asks My Lord! show me how Thou givest life to the dead. The meaning is quite clear, unless someone tries to hide it under metaphor.
Quran is not a recipe book which tells us each and every step and quantity of ingredients, but the flow of meaning in the verse you are referring is very much clear without any doubt IMO.
