Abu Juhaifah said: I asked Sayyiduna Ali, may Allah be pleased with him: O Commander of the Faithful! Do you have any revelation (from Allah) besides the Book of Allah? (Meaning, anything that is not present in the Holy Qur’an?) He replied: No, by Him Who split the grain and created the soul, I know nothing except the Qur’an, except for the understanding (and insight) which Allah grants to whomever He wills from His Book, and what is written on this scroll. I asked: What is written on this scroll? He said: The rulings of blood money (diyah), the release of captives, and the issue that a Muslim is not killed in retaliation for a disbeliever.
