Sahih Muslim Book 32, Hadith Number 6328.
Chapter : Grim warning to one who torments people without any valid justification.
Hisham reported on the authority of his father that Hisham b. Hakim b. Hizam happened to pass by people, the farmers of Syria, who had been made to stand in the sun. He said: What is the matter with them? They said: They have been detained for Jizya. Thereupon Hisham said: I bear testimony to the fact that I heard Allah’s Messenger (may peace be upon him) as saying: Allah would torment those who torment people in the world.
