Surah 3. Aal-Imran, Ayah 183

Lit., "with an offering which the fire consumes" -in other words, unless he conforms to Mosaic Law, which prescribes burnt offerings as an essential part of divine services. Although this aspect of the Law had been left in abeyance ever since the destruction of the Second Temple in Jerusalem, the Jews of post-Talmudic times were convinced that the Messiah promised to them would restore the Mosaic rites in their entirety; and so they refused to accept as a prophet anyone who did not conform to the Law of the Torah in every detail.

At the time of the martyrdom of John the Baptist and of Zachariah, of Jesus' exclamation, "O Jerusalem, Jerusalem, thou that killest the prophets" (Matthew xxiii, 37), and of the reference of Paul of Tarsus to the Jews "who killed their own prophets" (I Thessalonians ii, 15), the Second Temple was still in existence, and burnt offerings were a daily practice: thus, the refusal of the Jews to accept the prophets alluded to, culminating in their killing, could not be attributed to those prophets' lack of conformity with Mosaic Law.

 i.e., your forefathers.

Burn sacrifices figured in the Mosaic Law, and in the religious ceremonies long before Moses, but it is not true that the Mosaic Law laid down a fire from heavens on a burnt sacrifice as a test of the credentials of Prophets. Even if it had been so, did the Jews obey the Prophets who showed this Sign? In Leviticus ix. 23-24, we are told a burnt offering prepared by Moses and Aaron: "and there came a fire out from before the Lord, and consumed upon the altar the burnt offering and the fat." Yet the people rebelled frequently against Moses. Abel's offering (sacrifice) was probably a burnt offering: it was accepted by Allah, and he was killed by Cain out of jealousy: Gen. iv. 3-8. Mosaic sacrifices were no longer needed by the people of Jesus or the people of Muhammad.
