Narrated Abdullah ibn Amr ibn al-As: The Messenger of Allah صلی اللہ علیہ وسلم said: Muslims are equal in respect of blood. The lowest of them is entitled to give protection on behalf of them, and the one residing far away may give protection on behalf of them. They are like one hand over against all those who are outside the community. Those who have quick mounts should return to those who have slow mounts, and those who got out along with a detachment (should return) to those who are stationed. A believer shall not be killed for an unbeliever, nor a confederate within the term of confederation with him. Ibn Ishaq did not mention retaliation and equality in respect of blood.

Narrated Qays ibn Abbad: I and Ashtar went to Ali and said to him: Did the Messenger of Allah صلی اللہ علیہ وسلم give you any instruction about anything for which he did not give any instruction to the people in general? He said: No, except what is contained in this document of mine. Musaddad said: He then took out a document. Ahmad said: A document from the sheath of his sword. It contained: The lives of all Muslims are equal; they are one hand against others; the lowliest of them can guarantee their protection. Beware, a Muslim must not be killed for an infidel, nor must one who has been given a covenant be killed while his covenant holds. If anyone introduces an innovation, he will be responsible for it. If anyone introduces an innovation or gives shelter to a man who introduces an innovation (in religion), he is cursed by Allah, by His angels, and by all the people. Musaddad said: Ibn Abu Urubah's version has: He took out a document.
