Bulugh al-Maram

Abu Juhaifah (RAA) narrated, ‘I asked 'Ali: ‘Do you have any other Divine Revelation besides what is in the Qur’an? ’Ali said, ‘No. By Him Who made the grain split (germinate) and created the soul, we have nothing besides the Qur’an except the gift of understanding the Qur’an, which Allah gives a man, besides what is written in this manuscript. I said, ‘What is in this manuscript?’ ‘Ali said, ‘The regulations of Diyah (Blood money), the ransom for captives and the ruling that no Muslim should be killed in Qisas for killing a disbeliever.’ Related by Al-Bukhari. The previous tradition was also transmitted by Ahmad, An-Nasa’i and Abu Dawud on the authority of 'Ali with a different chain of narrators where he said, ‘The blood of one Muslim (his life) is equivalent to the blood of another Muslim (i.e. equal in Qisas and blood money), the protection of Allah is one (and is equally) extended to the most humble of the believers (i.e. if a Muslim gives protection to a man or to a group of men, they should all help him even is he was the most humble of them). Believers are all like one hand against their enemies. No believer is to be killed for a disbeliever (i.e. in Qisas), nor should one who has a covenant with the Muslims be killed while his covenant holds.’ Al-Hakim graded it as Sahih.
