So when they had both submitted their wills (to Allah), and he had laid him prostrate on his forehead (for sacrifice),
Note that the sacrifice was demanded of both
Abraham and Ismail. It was a trial of the will of the
father and the son. By way of trial the father had the
command conveyed to him in a vision. He consulted the
son. The son readily consented, and offered to stand true
to his promise if his self-sacrifice was really required.
The whole thing is symbolical. Allah does not require the
flesh and blood of animals (22:37), much less of human
beings. But he does require the giving of our whole being
to Allah, the symbol of which is that we should give up
something very dear to us, if Duty requires that sacrifice.
