The Messenger of Allah ﷺ did not entrust me with anything beyond what he gave the people, except for what is written on a sheet kept in the sheath of my sword. They kept pressing him until he produced the sheet, and on it was written, "The believers' lives are equal in retaliation. The protection granted by the lowest among them is binding upon them all, and they stand united against any outsider. A believer is not to be killed in retaliation for a disbeliever, nor is one under a covenant to be killed during the term of his covenant."
أخبرنا محمد بن بشار قال حدثنا الحجاج بن منهال قال حدثنا همام عن قتادة عن أبي حسان قال
ي ما عهد إلي رسول الله ﷺ بشيء دون الناس إلا في صحيفة في قراب سيفي فلم يزالوا به حتى أخرج الصحيفة فإذا فيها المؤمنون تكافأ دماؤهم يسعى بذمتهم أدناهم وهم يد على من سواهم لا يقتل مؤمن بكافر ولا ذو عهد في عهده
