While delivering a speech from the pulpit, ‘Ali (may Allah be pleased with him) said: “By Allah! We have no book to read except the Book of Allah and what is written in this scroll.” As he unrolled it, it showed a list of the types of camels to be given as blood-money and it contained other legal matters relating to the killing of game in the sanctuary of Makkah and the expiation for it. It also included the Prophet's statement declaring Madīnah as inviolable as Makkah, from Mount ‘Ayr to Mount Thawr. Whoever introduces a religious innovation in it, causes any harm to Muslims, or shelters an innovator will incur the curse of Allah, which means deprivation of His mercy, and the angels and all people will ask Allah to expel him from His mercy. Then, on the Day of Judgment, Allah, the Almighty, will not accept any prayer (obligatory or supererogatory), repentance, or ransom from him. Moreover, the protection given by any Muslim to a non-Muslim is valid, as long as it conforms to the relevant conditions. Once in place, it is prohibited to violate it. If anyone does so, he will be subject to the curse of Allah, which means he will be deprived of His mercy, and the angels and all people will ask the Almighty Lord to expel him from His mercy. Then, on the Day of Judgment, Allah, the Almighty, will not accept any prayer, obligatory or supererogatory, repentance, or ransom from him. If someone attributes himself to someone other than his real father or if a freed slave attributes himself to someone other than his master, he will incur the curse of Allah, the Almighty, which means deprivation of His mercy, and the angels and all people will ask Allah to expel him from His mercy. Then, on the Day of Judgment, Allah, the Almighty, will not accept any prayer (obligatory or supererogatory), repentance, or ransom from him. This is because these actions involve ingratitude and cause a loss of the rights to inheritance, allegiance, blood-money, and so on, and sever the ties of kinship.
