Narrated `Ali: We have no Book to recite except the Book of Allah (Qur'an) and this paper. Then `Ali took out the paper, and behold! There was written in it, legal verdicts about the retaliation for wounds, the ages of the camels (to be paid as Zakat or as blood money). In it was also written: 'Medina is a sanctuary from Air (mountain) to Thaur (mountain). So whoever innovates in it an heresy (something new in religion) or commits a crime in it or gives shelter to such an innovator, will incur the curse of Allah, the angels and all the people, and none of his compulsory or optional good deeds will be accepted on the Day of Resurrection. And whoever (a freed slave) takes as his master (i.e. be-friends) some people other than hi real masters without the permission of his real masters, will incur the curse of Allah, the angels and all the people, and none of his compulsory, or optional good deeds will be accepted on the Day of Resurrection. And the asylum granted by any Muslim is to be secured by all the Muslims, even if it is granted by one of the lowest social status among them; and whoever betrays a Muslim, in this respect will incur the curse of Allah, the angels, and all the people, and none of his Compulsory or optional good deeds will be accepted on the Day of Resurrection."

Narrated Ash-Shu`bi: Abu Juhaifa said, "I asked `Ali, 'Have you got any book (which has been revealed to the Prophet apart from the Qur'an)?' `Ali replied, 'No, except Allah's Book or the power of understanding which has been bestowed (by Allah) upon a Muslim or what is (written) in this sheet of paper (with me).' Abu Juhaifa said, "I asked, 'What is (written) in this sheet of paper?' `Ali replied, it deals with The Diyya (compensation (blood money) paid by the killer to the relatives of the victim), the ransom for the releasing of the captives from the hands of the enemies, and the law that no Muslim should be killed in Qisas (equality in punishment) for the killing of (a disbeliever).
