Ibrahim al-Taimi reported on the authority of his father: 'Ali b. Abi Talib (Allah be pleased with him) addressed us and said: He who thought that we have besides the Holy Qur'an anything else that we recite, he told a lie. And this document which is hanging by the sheath of the sword contains but the ages of the camels, and the nature of the wounds. He (Hadrat 'Ali) reported Allah's Apostle ﷺ as saying: Medina is sacred from 'Air to Thawr; So if anyone makes an innovation or accommodates an innovator, the curse of Allah, the angels, and all persons will fall upon him, and Allah will not accept any obligatory or supererogatory act as recompense from them. And the protection granted by the Muslims is one and must be respected by the humblest of them. If anyone makes a false claim to paternity, or being a client of other than his own masters, there is upon him the curse of Allah, the angels, and all the people. Allah will not accept from him any recompense in the form of obligatory acts or supererogatory acts. The hadith transmitted on the authority of Abu Bakr and Zabair ends with (these words): The humblest among them should respect it; and what follows after it is not mentioned there, and in the hadith transmitted by them (these words are) not found: (The document was hanging) on the sheath of his sword.
