سنن النسائي

It was narrated that Anas said: "The Messenger of Allah (ﷺ) said: 'A man from among the people of Paradise will be brought and Allah, the Mighty and Sublime, will say: "O son of Adam, how do you find your place (in Paradise)?" He would say: "O Lord, it is the best place." He will say: "Ask and wish (for whatever you want)." He would say: "I ask You to send me back to the world so that I may be killed in Your cause ten time" - because of what be sees of the virtue of martyrdom.'"
