Surah 7. Al-A'raf, Ayah 119

The proud ones of the Court-Pharaoh and his chiefs-were hard-hearted, and the exposure of the imposture only made them wreak their rage on those whom they could reach. On the other hand the effect on the humbler ones-those who had been made the dupes and instruments of the imposture-was quite different. Their conscience was awakened. They fell down to the ground in adoration of the Lord of the Worlds, and confessed their faith.
