`Ali bin Abi Talib (رضي الله عنه) addressed us and said: Whoever claims that we have something that we recite apart from the Book of Allah and this document in which are the ages of camels [to be given as diyah or blood money] and rulings concerning injuries, is lying. And in it the Prophet (ﷺ) said: `Madinah is sacred, the area between ‘Air and Thawr. Whoever commits any offence, or gives refuge to an offender, upon him will be the curse of Allah, the angels and all the people, and on the Day of Resurrection Allah will not accept any obligatory or nafil act of worship from him. Whoever claims to belong to someone other than his father or to belong to someone other than his masters (who manumitted him), upon him be the curse of Allah, the Angels and all the people, and on the Day of Resurrection Allah will not accept any nafil or obligatory act of worship from him. Protection granted by any Muslim is binding upon all of them, and may be given by the humblest of them.`
