Narrated `Amr bin Maimun: `Umar (after he was stabbed), instructed (his would-be-successor) saying, "I urge him (i.e. the new Caliph) to take care of those non-Muslims who are under the protection of Allah and His Apostle in that he should observe the convention agreed upon with them, and fight on their behalf (to secure their safety) and he should not over-tax them beyond their capability."

Narrated `Amr bin Maimun Al-Audi: I saw `Umar bin Al-Khattab (when he was stabbed) saying, "O `Abdullah bin `Umar! Go to the mother of the believers Aisha and say, `Umar bin Al-Khattab sends his greetings to you,' and request her to allow me to be buried with my companions." (So, Ibn `Umar conveyed the message to `Aisha.) She said, "I had the idea of having this place for myself but today I prefer him (`Umar) to myself (and allow him to be buried there)." When `Abdullah bin `Umar returned, `Umar asked him, "What (news) do you have?" He replied, "O chief of the believers! She has allowed you (to be buried there)." On that `Umar said, "Nothing was more important to me than to be buried in that (sacred) place. So, when I expire, carry me there and pay my greetings to her (`Aisha) and say, `Umar bin Al-Khattab asks permission; and if she gives permission, then bury me (there) and if she does not, then take me to the graveyard of the Muslims. I do not think any person has more right for the caliphate than those with whom Allah's Apostle (p.b.u.h) was always pleased till his death. And whoever is chosen by the people after me will be the caliph, and you people must listen to him and obey him," and then he mentioned the name of `Uthman, `Ali, Talha, Az-Zubair, `Abdur-Rahman bin `Auf and Sa`d bin Abi Waqqas. By this time a young man from Ansar came and said, "O chief of the believers! Be happy with Allah's glad tidings. The grade which you have in Islam is known to you, then you became the caliph and you ruled with justice and then you have been awarded martyrdom after all this." `Umar replied, "O son of my brother! Would that all that privileges will counterbalance (my short comings), so that I neither lose nor gain anything. I recommend my successor to be good to the early emigrants and realize their rights and to protect their honor and sacred things. And I also recommend him to be good to the Ansar who before them, had homes (in Medina) and had adopted the Faith. He should accept the good of the righteous among them and should excuse their wrongdoers. I recommend him to abide by the rules and regulations concerning the Dhimmis (protectees) of Allah and His Apostle, to fulfill their contracts completely and fight for them and not to tax (overburden) them beyond their capabilities."
