"According to Islamic principles, when a man is accused of heresy, he is given the choice between repentance and punishment"

This quote by Naguib Mahfouz talks to the Islamic concepts of justice and mercy. According to Islamic law, when a guy is accused of heresy, he is offered the chance to repent and be forgiven for his misdeeds. This is an example of the Islamic concept of mercy, which is based on the idea that God is merciful and flexible. If the accused chooses to repent, then he is forgiven and no penalty is provided. Nevertheless, if the implicated does not repent, then he goes through punishment. This penalty is implied to be a deterrent to others, and to advise them of the effects of their actions. The Islamic concepts of justice and mercy are indicated to ensure that justice is served, while also permitting the possibility of redemption and forgiveness.
