It was narrated that Abu Juhaifah said:
We asked ‘Ali (رضي الله عنه): Do you have something from the Messenger of Allah (ﷺ) apart from the Qur`an? He said: No, by the One who split the seed and created the soul, except the understanding that Allah, may He be glorified and exalted, helps a person to acquire of the Qur`an or what is in the document.I said: What is in the document? He said: Diyah (blood money), ransom of prisoners and muslim should be killed in retaliation for a kafir.
