Sha'bi (may Allah have mercy on him) and Ibrahim Nakha'i (may Allah have mercy on him) said: If the People of the Book come to the Muslim rulers for judgment, then the ruler may choose to judge between them or may choose to turn away from them. But if he judges, then he should judge according to the law revealed by Allah, the Mighty and Majestic.
