Al-Lu'lu Wal-Marjan 868 — The Book of Hajj (Pilgrimage to Makka)

Narrated 'Alî رضي الله عنه when he addressed people while he was standing on a brick pulpit and carrying a sword from which was hanging a scroll. He said, "By Allâh, we have no book to read except Allâh'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: 'Al-Madîna is a sanctuary from 'Air (mountain) to such and such place, so whoever innovates in it a heresy or commits a sin therein, he will incur the Curse of Allâh, the angels and all the people, and Allâh will not accept his compulsory or optional good deeds.' There was also written in it: 'Asylum (pledge of protection) granted by any Muslim is one and the same, (even a Muslim of the lowest status) is to be secured and respected by all other Muslims, and whoever betrays a Muslim (by violating the pledge) will incur the Curse of Allâh, the angels, and all the people, and Allâh will not accept his compulsory or optional good deeds.' There was also written in it: 'Whoever (freed slave) takes as masters other than his real masters (manumitters) without their permission, will incur the Curse of Allâh, the angels, and all the people, and Allâh will not accept his compulsory or optional good deeds.' ( Sahîh Al-Bukhâri, Hadîth No. 403, Vol. 9)
