The next morning, at the mountain, the Khalif came on his horse with many soldiers. His minister and advisers came also. Anba Abraham was there with the bishops, priests and the elders, all carrying their censors, crosses and candles. The Patriarch led the people in prayer. Simon stood humbly behind him. After the reading of the gospel, the Copts chanted in one voice Kerialeison (Lord have mercy) forty one times, bowing down at the end with one accord. Every time they raised their heads the high mountain moved upward by the power of God.

And every time they bowed their heads the mountain came down again! It was a terrifying scene for the Khalif and his companions. The Khalif pleaded the Patriarch to stop. The Patriarch stopped and it became silent. A few moments of silence passed. Then the Copts burst into a loud cry praising God. When the Copts finished the Khalif confessed to the Copts that they follow the one true God. The Khalif insisted on paying a large sum of money to apologize for his troubles. The Patriarch refused and asked instead for permission to fix the Al Muallaqa church.

After the miracle, the Khalif became Christian. Simon the Tanner disappeared after the mountain stopped moving.
