Narrated Ibrahim At Tamii's father:

Ali addressed us while he was standing on a brick pulpit and carrying a sword from which was hanging a scroll He said "By Allah, we have no book to read except Allah's Book and whatever is on this scroll," And then he unrolled it, and behold, in it was written what sort of camels were to be given as blood money, and there was also written in it: 'Medina is a sanctuary form 'Air (mountain) to such and such place so whoever innovates in it an heresy or commits a sin therein, he will incur the curse of Allah, the angles, and all the people and Allah will not accept his compulsory or optional good deeds.' There was also written in it: 'The asylum (pledge of protection) granted by any Muslims is one and the same, (even a Muslim of the lowest status is to be secured and respected by all the other Muslims, and whoever betrays a Muslim in this respect (by violating the pledge) will incur the curse of Allah, the angels, and all the people, and Allah will not accept his compulsory or optional good deeds.' There was also written in it: 'Whoever (freed slave) befriends (takes as masters) other than his real masters (manumitters) without their permission will incur the curse of Allah, the angels, and all the people, and Allah will not accept his compulsory or optional good deeds. ' (See Hadith No. 94, Vol. 3)
