سنن ابن ماجه

It was narrated from 'Amr bin Shu'aib, from his father, from his grandfather that the Messenger of Allah (ﷺ) said: “The hand of the Muslims is over others, and their blood and wealth is equal in value. The (asylum granted by) the lowest of them applies to the Muslims, and the Muslims return (the spoils of war) to the farthest of them.”
