Acts 6:9–14 (ASV)
9But there arose certain of them that were of the synagogue called the synagogue of the Libertines, and of the Cyrenians, and of the Alexandrians, and of them of Cilicia and Asia, disputing with Stephen. 10And they were not able to withstand the wisdom and the Spirit by which he spake. 11Then they suborned men, who said, We have heard him speak blasphemous words against Moses, and against God. 12And they stirred up the people, and the elders, and the scribes, and came upon him, and seized him, and brought him into the council, 13and set up false witnesses, who said, This man ceaseth not to speak words against this holy place, and the law: 14for we have heard him say, that this Jesus of Nazareth shall destroy this place, and shall change the customs which Moses delivered unto us.

With a pistol to his head, Kazim still wouldn't recant his faith in Jesus; he was happy to die if God wills so.

But through it all, Kazim's only sadness was his inability to read the Bible due to his swollen eyes.
A believer was accused falsely of destroying the idols in a village temple and was on the strength of that false testimony fined and forced to repair the destroyed temple.
