Musnad Abi Ya'la 4757 — she said: I found a writing in the hilt

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: "I found a writing in the hilt of the sword of the Messenger of Allah (peace and blessings be upon him), in which it was written: 'The most insolent of people is the one who strikes someone who did not strike him, and the man who kills (in retaliation) someone other than the actual killer, and the man who leaves his true benefactors and takes others as his patrons. Whoever does that has disbelieved in Allah and His Messenger; Allah Almighty will accept from him neither an obligatory nor a voluntary deed. The blood of all the believers is equal (in blood money and retaliation), and even the lowest of them can take on a responsibility on behalf of them all (by granting someone protection). A Muslim is not to be killed for a disbeliever, nor is a person under a covenant to be killed during the term of his covenant. The followers of two different religions do not inherit from one another. A woman is not to be married while her paternal aunt or her maternal aunt (is married to the same man, combining them in one marriage). There is no prayer after Asr until the sun sets. And no woman should travel a journey of three nights without her mahram.'"
This report was transmitted by Amrah bint Abd al-Rahman (may Allah have mercy on her) from Sayyidah Aishah (may Allah be pleased with her).
