ALI 'IMRAN — Ayat 183

الَّذِينَ قَالُواْ إِنَّ اللّهَ عَهِدَ إِلَيْنَا أَلاَّ نُؤْمِنَ لِرَسُولٍ حَتَّىَ يَأْتِيَنَا بِقُرْبَانٍ تَأْكُلُهُ النَّارُ قُلْ قَدْ جَاءكُمْ رُسُلٌ مِّن قَبْلِي بِالْبَيِّنَاتِ وَبِالَّذِي قُلْتُمْ فَلِمَ قَتَلْتُمُوهُمْ إِن كُنتُمْ صَادِقِينَ

[They are] those who said, "Indeed, Allah has taken our promise not to believe any messenger until he brings us an offering which fire [from heaven] will consume." Say, "There have already come to you messengers before me with clear proofs and [even] that of which you speak. So why did you kill them, if you should be truthful?"
