Abu Juhayfa reported,

I asked Ali رضي الله عنه, "Do you have anything that is not in the Quran?"Ibn Uyayna once said it as, "anything that the people do not have?"Ali replied, "By the One who split the seed and created the soul, we have nothing except what is in the Quran, except for an understanding that a man is granted concerning his Book, and what is in this document."I asked, "What is in the document?"He said, "The rules of blood-money, the ransoming of captives, and that a Muslim is not to be killed in retaliation for a disbeliever."

Sahih

عن أبي جحيفة قال

سألت عليا رضي الله عنه: هل عندكم شيء مما ليس في القرآن؟ وقال ابن عيينة مرة: ما ليس عند الناس؟ فقال: والذي فلق الحبة وبرأ النسمة ما عندنا إلا ما في القرآن، إلا فهما يعطى الرجل في كتابه، وما في الصحيفة. قلت: وما في الصحيفة؟ قال: العقل، وفكاك الأسير، وأن لا يقتل مسلم بكافر.
