Text: On the mosque floor rests a huge ancient slab, the Rock itself, on which Abraham prepared to sacrifice his son Isaac (but was given a last-minute reprieve by an angel) and from which the prophet Mohammed roseto Heaven during his dream-visit to Jeru?γalem.
Entailment: The rock on which Abraham was ordered to sacrifice his son now resides on the floor of the mosque.
Contradiction: The rock where Abraham was ordered to sacrifice his son is the stuff of legend, and no one claims to know where it is today.
