the safrifice of Ismael

And when he reached with him [the age of] exertion, he said, "O my son, indeed I have seen in a dream that I [must] sacrifice you, so see what you think." He said, "O my father, do as you are commanded. You will find me, if Allah wills, of the steadfast." And when they had both submitted and he put him down upon his forehead, We called to him, "O Abraham, You have fulfilled the vision." Indeed, We thus reward the doers of good.
